+++ This bug was initially created as a clone of Bug #215443 +++ Description of problem: I'm seeing a Apache segfault problem on two servers that cropped up once I upgraded my desktop to Fedora Core v6. The segfault occurs 80% of the time when it tries to auth me. This setup has been working for over a year with no problems until I upgraded my desktop to FC6. My co-worker running FC5 continues to work fine (as do Windows clients). Fedora Core v6 ships and uses MIT kerberos v1.5 (my guess is the MIT kerb version is relevant). The two servers I'm using are: * Fedora Core v4 + mit krb 1.4.2 + Apache httpd-2.0.54 + mod_auth_krb 5.2 (I've tried 5.0 and 5.1 as well) * Debian Sarge + mit krb 1.3 + Apache 2.0.54 + mod_auth_krb 5.0-rc6 On the Fedora server I was able to get this backtrace: (gdb) bt full #0 0x00dda402 in __kernel_vsyscall () No symbol table info available. #1 0x00ac6f90 in raise () from /lib/libc.so.6 No symbol table info available. #2 0x00ac8678 in abort () from /lib/libc.so.6 No symbol table info available. #3 0x00afc230 in __libc_message () from /lib/libc.so.6 No symbol table info available. #4 0x00b04d0d in realloc () from /lib/libc.so.6 No symbol table info available. #5 0x0038a2dd in decode_MechTypeList ( p=0x99f1242 "\006\t*\206H\202�\022\001\002\002�\202\002\031\004\202\002\025`\202\002\021\006\t*\206H\206�\022\001\002\002\001", len=11, data=0xa0c37b8, size=0xbfd3e014) at spnegokrb5/asn1_MechTypeList.c:61 ret = 18 reallen = 29 l = 7 e = Variable "e" is not available.
