We have following code in Curl.
...
SecCertificateCopyCommonName(cert, &common_name);
#endif
if(CFStringCompare(common_name, label_cf, 0) == kCFCompareEqualTo)
When the SecCertificateCopyCommonName function fails, it does not have to leave common_name in valid, state. So CFStringCompare is using the invalid result, hence causing EXC_BAD_ACCESS.
Fix is to check return value of the function.
