Re: [Fastcgipp-users] Segfault on apache shutdown

[Riccardo Campisano]

Thanks for your fast reply.

Running the application from the command line don't cause any problem. The git source was built using the bootstrap script in the package, however the version fastcgi++-2.0beta-6852ded9 built with ./configure && make has the same problem. The app run on a debian stable (a chrooted environment) with boost 1.35.


I add your "debug" code, the source of the application is at the end of this email.

When I start the apache end kill it without call the fcgi application on the browser, no error is reported. When I start the apache, call the fcgi, this log is reported (as correct):


cat /tmp/errlog 
[2011-Aug-12 13:58:13] Debug 0
[2011-Aug-12 13:58:13] Debug 1
[2011-Aug-12 13:58:13] Echo::response()

Whenever I stop apache after a call on the fcgi application, the error is reported by syslogd at /var/log/message


Aug 12 13:59:30 ubuntudev kernel: [154439.084532] test.fcgi[6573]: segfault at 0 ip b77db2e8 sp bfd0e0d0 error 4 in libfastcgipp.so.2.0.0[b77d2000+73000]

Thanks, and sorry for my English
Riccardo
