Dear Bug Team! My 21.5 windows build crashes with the following recipe: xemacs -vanilla z.el z.el contains: (defun remove-block (header footer) "Remove the block of text delineated by header and footer." (goto-char (point-max)) (let* ((s (search-backward header (point-min) t)) (e (search-forward footer (point-max) t))) (and s e (kill-region s e)))) (find-file "/tmp/gnuclient-test") (insert-string " (setq package-get-package-index-file-location \"e:\\XEmacs\\XEmacs-21.5-b28\\etc\") ") (goto-char (point-max)) (remove-block "\n;;; Lines added by gnuclient_setup\n" "\n;;; End of gnuclient_setup addition\n") M-x eval-current-buffer and boom! Note that the search should fail. My lisp is a little rusty and I could easily have made a mistake in the remove-block routine, but I don't think a crash should occur. Note that 21.4 behaves as expected. Lisp backtrace follows: # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) # (unwind-protect ...) search-backward("\n;;; Lines added by gnuclient_setup\n" 1 t) (let* ((s (search-backward header (point-min) t)) (e (search-forward footer (point-max) t))) (and s e (kill-region s e))) # bind (footer header) remove-block("\n;;; Lines added by gnuclient_setup\n" "\n;;; End of gnuclient_setup addition\n") # (unwind-protect ...) # (unwind-protect ...) # bind (standard-output) eval-buffer(#<buffer "z.el"> nil) # bind (printflag) #<compiled-function (&optional printflag) "...(5)" [printflag eval-buffer] 3 1020680 nil>() call-interactively(eval-current-buffer) command-execute(eval-current-buffer t) # bind (_execute_command_keys_ _execute_command_name_ prefix-arg) execute-extended-command(nil) # bind (command-debug-status) call-interactively(execute-extended-command) (dispatch-event "[internal]") # (condition-case ... . error) # (catch top-level ...) ... and here is the C backtrace: assert_failed(const char * 0x0165473c, int 1487, const char * 0x016546fc) line 3982 simple_search(buffer * 0x0282e8a8, unsigned char * 0x0082e504, long 36, long 2, long 1, long -1, long 25747920) line 1487 + 107 bytes search_buffer(buffer * 0x0282e8a8, long 42191620, long 81, long 1, long -1, int 0, long 25747920, long 25746728, int 0) line 1409 + 33 bytes search_command(long 42191620, long 3, long 25274672, long 25275488, long 25275488, int -1, int 0, int 0) line 1161 + 151 bytes Fsearch_backward(long 42191620, long 3, long 25274672, long 25275488, long 25275488) line 2122 + 31 bytes Feval(long 42189844) line 3676 + 309 bytes FletX(long 42190024) line 1046 + 31 bytes Feval(long 42189820) line 3648 + 13 bytes Fprogn(long 42189760) line 954 + 9 bytes funcall_lambda(long 42190144, int 2, long * 0x0082ebc8) line 4284 + 9 bytes Feval(long 41303424) line 3788 + 20 bytes readevalloop(long 41055776, long 40945204, long (long)* 0x010bcffa Feval(long), int 0) line 1467 + 7 bytes Feval_buffer(long 41055776, long 25275488) line 1518 + 58 bytes Ffuncall(int 3, long * 0x0082ef00) line 3928 + 108 bytes execute_optimized_program(const unsigned char * 0x02872fd0, int 3, long * 0x01993cc4) line 862 + 16 bytes funcall_compiled_function(long 27015892, int 0, long * 0x0082f24c) line 3517 + 73 bytes Ffuncall(int 1, long * 0x0082f248) line 3967 + 17 bytes apply1(long 27015892, long 25275488) line 4549 + 11 bytes Fcall_interactively(long 25242608, long 25274672, long 25275488) line 459 + 13 bytes Fcommand_execute(long 25242608, long 25274672, long 25275488) line 3138 + 17 bytes Ffuncall(int 3, long * 0x0082f56c) line 3928 + 142 bytes execute_optimized_program(const unsigned char * 0x02851e38, int 7, long * 0x0197c604) line 862 + 16 bytes funcall_compiled_function(long 26955304, int 1, long * 0x0082f890) line 3517 + 73 bytes Ffuncall(int 2, long * 0x0082f88c) line 3967 + 17 bytes Fcall_interactively(long 25127936, long 25275488, long 25275488) line 994 + 22 bytes Fcommand_execute(long 25127936, long 25275488, long 25275488) line 3138 + 17 bytes execute_command_event(command_builder * 0x01e97738, long 42218100) line 4288 + 25 bytes Fdispatch_event(long 42218100) line 4600 + 79 bytes Fcommand_loop_1() line 600 + 9 bytes command_loop_1(long 25275488) line 511 condition_case_1(long 25272416, long (long)* 0x0108ff70 command_loop_1(long), long 25275488, long (long, long)* 0x0108fbc6 cmd_error(long, long), long 25275488) line 1946 + 7 bytes command_loop_3() line 262 + 35 bytes command_loop_2(long 25275488) line 277 internal_catch(long 25006832, long (long)* 0x0108fd16 command_loop_2(long), long 25275488, int * volatile 0x00000000, long * volatile 0x00000000, long * volatile 0x00000000) line 1552 + 7 bytes initial_command_loop(long 25275488) line 313 + 29 bytes xemacs_21_5_b28_i586_pc_win32(int 3, unsigned short * * 0x0082fee4, unsigned short * * 0x00000000, int 0) line 2669 main(int 3, char * * 0x00f42768, char * * 0x00f42d50) line 3114 XEMACS! mainCRTStartup + 227 bytes KERNEL32! 7c816fd7() It's easy for me to reproduce this and I can poke around in the debugger to answer any questions.
