Not especially. Having symbols would help. It's going to be something in
foreach() in lib/cyrusdb_quotalegacy.c, though, since that's the only
place you'd be using the system glob().
I suppose, for simplicity, you can just add a
before and after
/* strip off the qr specific path and replace with pattern */
sprintf(strstr(quota_path, FNAME_QUOTADIR) + strlen(FNAME_QUOTADIR),
And see what 2 lines you get just before the crash, as a way of cheating.
