Hi,

I implemented some stress tests which include parallel calls of
soup_session_sync_new. The result is a segfault under Solaris. The
crashing test runs under libsoup 2.2 because this is still the default
version on Solaris.

lwp #2, #3 or #4 causing the segfault. All other threads are just
waiting. Any ideas what's going on?
