I'm not sure whether someone has reported this. Anyway 21.2.6 dies in redisplay when built with mule under mswindows and trying to print out the border glyphs.

This is easy to reproduce - just do xemacs -q. andy Breakpoint 1, 0x6a4b38 in abort () (gdb) where #0 0x6a4b38 in abort () #1 0x4536a5 in assert_failed (file=0x4bfd84 "objects.h", line=144, expr=0x4c00b5 "RECORD_TYPEP (obj, lrecord_font_instance) || MARKED_RECORD_P (obj)") at emacs.c:2630 #2 0x4c0150 in error_check_font_instance (obj={gu = {type = Lisp_Type_Record, val = 2472074}, s = {bits = 0, val = 4944148}, u = {bits = 0, val = 4944148}, ui = 9888296, i = 9888296, v = 0x96e228, cv = 0x96e228}) at objects.h:144 #3 0x48097c in mswindows_output_string (w=0x100d3400, dl=0x101d13f0, buf=0x101ae260, xpos=632, xoffset=0, clip_start=632, width=8, findex=12) at redisplay-msw.c:540 #4 0x48250e in mswindows_output_display_block (w=0x100d3400, dl=0x101d13f0, block=0, start=0, end=80, start_pixpos=0, cursor_start=0, cursor_width=0, cursor_height=0) at redisplay-msw.c:1243 #5 0x57d3a9 in output_display_line (w=0x100d3400, cdla=0x101617c0, ddla=0x101617a0, line=14, force_start=-1, force_end=-1) at redisplay-output.c:686 #6 0x57ecbf in redisplay_output_window (w=0x100d3400) at redisplay-output.c:1315 #7 0x56dad6 in redisplay_window (window={gu = {type = Lisp_Type_Record, val = 67325184}, s = {bits = 0, val = 134650368}, u = {bits = 0, val = 134650368}, ui = 269300736, i = 269300736, v = 0x100d3400, cv = 0x100d3400}, skip_selected=0) at redisplay.c:5242 #8 0x56dfd4 in redisplay_frame (f=0x100d3000, preemption_check=0) at redisplay.c:5418 #9 0x56e37d in redisplay_device (d=0x1013bf00) at redisplay.c:5502 #10 0x56e93d in redisplay_without_hooks () at redisplay.c:5618 #11 0x56eb6c in redisplay () at redisplay.c:5686 #12 0x4d6f87 in Fsit_for (seconds={gu = {type = Lisp_Type_Int_Even, val = 0}, s = {bits = 1, val = 0}, u = {bits = 1, val = 0}, ui = 1, i = 1, v = 0x1, cv = 0x1}, nodisplay={gu = {type = Lisp_Type_Record, val = 1983489}, s = {bits = 0, val = 3966978}, u = {bits = 0, val = 3966978}, ui = 7933956, i = 7933956, v = 0x791004, cv = 0x791004}) at event-stream.c:2814 #13 0x45aff2 in Ffuncall (nargs=2, args=0x2cff268) at eval.c:3189 #14 0x4195ca in execute_optimized_program (program=0x2cff324 "À\tÂÃ#\024Å \210eb\210ÆÇ!\210È \026\tÃ\207", stack_depth=4, constants_data=0x709de4) at bytecode.c:750 #15 0x41f8ed in Fbyte_code (instructions={gu = {type = Lisp_Type_Record, val = 1845093}, s = {bits = 0, val = 3690186}, u = {bits = 0, val = 3690186}, ui = 7380372, i = 7380372, v = 0x709d94, cv = 0x709d94}, constants={gu = {type = Lisp_Type_Record, val = 1845109}, s = {bits = 0, val = 3690218}, u = {bits = 0, val = 3690218}, ui = 7380436, i = 7380436, v = 0x709dd4, cv = 0x709dd4}, stack_depth={gu = {type = Lisp_Type_Int_Even, val = 2}, s = {bits = 1, val = 4}, u = {bits = 1, val = 4}, ui = 9, i = 9, v = 0x9, cv = 0x9}) at bytecode.c:2398 #16 0x45a62b in Feval (form={gu = {type = Lisp_Type_Record, val = 1845087}, s = {bits = 0, val = 3690174}, u = {bits = 0, val = 3690174}, ui = 7380348, i = 7380348, v = 0x709d7c, cv = 0x709d7c}) at eval.c:2986 #17 0x4570b6 in internal_catch (tag={gu = {type = Lisp_Type_Record, val = 2009944}, s = {bits = 0, val = 4019888}, u = {bits = 0, val = 4019888}, ui = 8039776, i = 8039776, v = 0x7aad60, cv = 0x7aad60}, func=0x459efc <Feval>, arg={gu = {type = Lisp_Type_Record, val = 1845087}, s = {bits = 0, val = 3690174}, u = {bits = 0, val = 3690174}, ui = 7380348, i = 7380348, v = 0x709d7c, cv = 0x709d7c}, threw=0x0) at eval.c:1315 #18 0x41b97c in execute_rare_opcode (stack_ptr=0x2cff618, program_ptr=0x709e84 "\210*rÌÆ!q\210Í \210\016\016;«\005\016\016c\210ÏÄ!)\207\016\020ÑÄ\211\211\211\211\211\036\02 2\036\023\036\024\036\025\036\026\036\027\036\030\036\031\b\205\237", opcode=Bcatch) at bytecode.c:1256 #19 0x419051 in execute_optimized_program (program=0x709e60 "\b¬;\t?\205ó", stack_depth=8, constants_data=0x709c4c) at bytecode.c:660 #20 0x41897c in funcall_compiled_function (fun={gu = {type = Lisp_Type_Record, val = 1845000}, s = {bits = 0, val = 3690000}, u = {bits = 0, val = 3690000}, ui = 7380000, i = 7380000, v = 0x709c20, cv = 0x709c20}, nargs=0, args=0x2cff7bc) at bytecode.c:527 #21 0x45b267 in Ffuncall (nargs=1, args=0x2cff7b8) at eval.c:3221 #22 0x4195ca in execute_optimized_program (program=0x7092f4 "\bA\031ÂÃ\034\035Æ\t!\021ÇÈ!«\004É \210\016\n«\020\016\013¬\fÌÍÎ\016\n!ÏQ!
