[Quickfix-developers] QF 1.5.0: core dump running unit tests

[Joerg T. <Joe...@ma...>]

Hello,

finally I compiled QF 1.5.0 using GCC 3.0 (we had a busy time...) and
all went fine -- unit I ran the unit tests:

$ ./runut 9999
<ut>
   <output>
.....................................................................................F./runut: 
line 6: 24178 Segmentation fault      (core dumped) bin/ut -p $1

Looking into the core:

The core appears on entry to the SocketMonitor destructor. May this be
a compiler problem? Any ideas are welcome.

In the meantime, I try to do this with the GCC 3.2.

Cheers, Jörg
