[Devel] Re: QOP workaround in uac_auth() doesn't work around...

[Thomas Gelf]

Hi Bodgan,

thanks for your reply! I'm probably unable to do the tests before the
end of the next week as I'm really really busy right now. But I can
confirm that OpenSER keeps crashing with "auth->qop = val;". To fix
the problem I need to do nothing but simply recompiling uac.so with
this line commented out.

Btw: this is also true for older versions (tested it for example some
time ago with an early pre-1.1 CVS-Version).

Best regards,
Thomas Gelf
