Thanks again, Aidan My dual W32/X11 version of xemacs, when running in W32 mode, used to crash also when calling M-x info and then trying to scroll down a couple of pages. This is fixed with your hint. By the way line 563 get's triggered in that case. This will also be applied ASAP against the official cygwin version of xemacs. Ciao Volker

Ar an t-aonú lá is triochad de mí Iúil, scríobh Stephen J. Turnbull: That’s it--it’s a mundane stack overflow. The length of the instructions string is 79648, we try to allocate twice that (= 160k) on the stack, Windows refuses. Mule-UCS is horrible code. The below makes (require 'un-define) work for me. I’m not sure that it doesn’t leak memory in the various error cases, unhappily. =================================================================== RCS file: /pack/xemacscvs/XEmacs/xemacs/src/bytecode.c,v retrieving revision 1.14.2.2 diff -u -r1.14.2.2 bytecode.c --- bytecode.c 2005/01/31 02:55:04 1.14.2.2 +++ bytecode.c 2006/07/31 10:36:05 ＠＠ -1624,7 +1624,7 ＠＠ int from; int to; }; - struct jump * const jumps = alloca_array (struct jump, comfy_size); + struct jump * const jumps = xnew_array (struct jump, comfy_size); struct jump *jumps_ptr = jumps; Opbyte *program_ptr = program; ＠＠ -1868,6 +1868,7 ＠＠ /* *program_ptr++ = 0; */ *program_length = program_ptr - program; + xfree(jumps); } /* Optimize the byte code and store the optimized program, only -- Santa Maradona, priez pour moi!

Comments? Does anyone think the below patch will have a noticeable effect on the speed byte compiler? Barring any concerns, I will check this in for 21.4.20. - Vin Aidan Kehoe <kehoea(a)parhasard.net&gt; writes: =================================================================== RCS file: /pack/xemacscvs/XEmacs/xemacs/src/bytecode.c,v retrieving revision 1.14.2.2 diff -u -r1.14.2.2 bytecode.c --- bytecode.c 2005/01/31 02:55:04 1.14.2.2 +++ bytecode.c 2006/07/31 10:36:05 ＠＠ -1624,7 +1624,7 ＠＠ int from; int to; }; - struct jump * const jumps = alloca_array (struct jump, comfy_size); + struct jump * const jumps = xnew_array (struct jump, comfy_size); struct jump *jumps_ptr = jumps; Opbyte *program_ptr = program; ＠＠ -1868,6 +1868,7 ＠＠ /* *program_ptr++ = 0; */ *program_length = program_ptr - program; + xfree(jumps); } /* Optimize the byte code and store the optimized program, only

Ar an chéad lá de mí Lúnasa, scríobh Stephen J. Turnbull: Or breaking just after the xnew_array, doing a garbage-collect, and making sure that the array is now garbage. Avoiding such objects being garbage-collected is the point of GCPRO, after all. -- Santa Maradona, priez pour moi!

Ar an chéad lá de mí Lúnasa, scríobh Vin Shelton: invalid_byte_code_error _is_ an alternate return path from the routine in question, and it was that I was worried about. Hmm--the same reasoning applies to leaking memory as a result of invalid_byte_code_error being called before xfree(), but more so, since the only people likely to specify invalid byte code to the interpreter are either working on the interpreter or have just loaded a GNU Emacs byte-compiled file. -- Santa Maradona, priez pour moi!

Ar an dara lá de mí Lúnasa, scríobh Ben Wing: Steve doesn’t have Cygwin, which is where this behaviour happens. I was wrong in what I said on the size of the allocation; it’s 79648 times two _times the size of an int,_ which is 637k. If changing to malloc() solves the problem, which seems to be the case, doing something so invasive is overkill, I think. -- Santa Maradona, priez pour moi!
