krb5_cc_default crash

[Tim Vega]

Hi,

I'm trying to get S4U2proxy to work with mod_auth_kerb. I compiled the patch here,http://sourceforge.net/p/modauthkerb/mailman/message/28531618/, into mod_auth_kerb but it crashes on a call to krb5_cc_default.

The offending line is line 283 of stdcc.c:
err = cc_initialize (&gCntrlBlock, ccapi_version_max, &gCCVersion, NULL);

The top of the stack trace is:
                00000000()

Disassembly (the break is at the add instruction):
        err = cc_initialize (&gCntrlBlock, ccapi_version_max, &gCCVersion, NULL);
6647164A  push        0
6647164C  push        offset _gCCVersion (665A5DE4h)

66471653  push        offset _gCntrlBlock (665A5DE0h)
66471658  call        dword ptr [_pcc_initialize (665A7048h)]
6647165E  add         esp,10h
66471661  mov         dword ptr [err],eax

_pcc_initialize watched values:
                                _pcc_initialize    0x665a7048 _pcc_initialize           void *
                                *(long *)_pcc_initialize 0              long

Any help would be greatly appreciated!
