I just tried to build Emacs 23.4, and I'm sorry to say that neither the optimized build nor the unoptimized one crash for me. They both build just fine and come up without crashing. > Backtrace from optimized build with debug symbols: > > Program received signal SIGSEGV, Segmentation fault. > 0x010719e8 in lookup_volume_info (root_dir=0x88fcdc "d:\\") at w32.c:2051 > 2051 if (xstrcasecmp (info->root_dir, root_dir) == 0) What's the problem that causes the crash? Is `info' or `info->root_dir' a NULL pointer or something? If nothing else gives a clue, diff Emacs 23.4 sources against 23.3.90, and then apply the diffs one by one until you get the crash. This should pinpoint the change which causes this.
