Re: [Dovecot] Seg fault in dovecot/auth 2.0.15

Your message was discarded by mailman, probably because it was html-only. Anyway:

OK, so "auth_request->userdb->userdb->iface->lookup" should call vpopmail_lookup(), it's not NULL as this says:

...

(gdb) bt full #0 0x00000000 in ?? ()

So something's going strangely wrong. Maybe gcc optimizations cause this and the real problem happens later. Try compiling auth process with optimizations:

• Remove -O2 from src/auth/Makefile
• cd src/auth ; make clean ; make ; make install

Is the backtrace different?
