Today Emacs finally crashed, and gdb seems to reveal some more information than the previous core dumps. Please let me know if the stuff below is of any help. The crash occurred while I was moving down a planner-mode buffer using the page down key. I tried to save a core file for future analysis, but gdb wouldn't let me, causing the following error: (gdb) generate-core-file warning: cannot close "core.5044": Invalid operation Can't create a corefile Is that a known Cygwin limitation? In any case, I'll try to keep gdb open for a while. I'll be happy to run additional gdb commands as you see fit. regards, Markus Program received signal SIGSEGV, Segmentation fault. 0x00000005e20450f0 in cygfontconfig-1!FcObjectLookupOtherTypeById () from /usr/bin/cygfontconfig-1.dll (gdb) info threads Id Target Id Frame 9 Thread 5044.0x1024 0x00000000777012fa in ntdll!ZwWaitForSingleObject () from /cygdrive/c/WINDOWS/system32/ntdll.dll 8 Thread 5044.0x1330 0x00000000777012fa in ntdll!ZwWaitForSingleObject () from /cygdrive/c/WINDOWS/system32/ntdll.dll 6 Thread 5044.0x1350 0x00000000777015fa in ntdll!ZwDelayExecution () from /cygdrive/c/WINDOWS/system32/ntdll.dll 5 Thread 5044.0x132c 0x00000000777012fa in ntdll!ZwWaitForSingleObject () from /cygdrive/c/WINDOWS/system32/ntdll.dll 4 Thread 5044.0x134c 0x000000007770186a in ntdll!ZwWaitForMultipleObjects () from /cygdrive/c/WINDOWS/system32/ntdll.dll 3 Thread 5044.0x1008 0x000000007770186a in ntdll!ZwWaitForMultipleObjects () from /cygdrive/c/WINDOWS/system32/ntdll.dll 2 Thread 5044.0x13f4 0x000000007770131a in ntdll!ZwReadFile () from /cygdrive/c/WINDOWS/system32/ntdll.dll * 1 Thread 5044.0x13ac 0x00000005e20450f0 in cygfontconfig-1!FcObjectLookupOtherTypeById () from /usr/bin/cygfontconfig-1.dll (gdb) thread apply all bt Thread 9 (Thread 5044.0x1024): #0 0x00000000777012fa in ntdll!ZwWaitForSingleObject () from /cygdrive/c/WINDOWS/system32/ntdll.dll #1 0x000007fefd6d10dc in WaitForSingleObjectEx () from /cygdrive/c/WINDOWS/system32/KERNELBASE.dll #2 0x0000000000000000 in ??
