Re: [Firebird-devel] FB-SS-Linux - RC7 debug Seg fault stack trace

[Alex <a-...@gm...>]

Here is another stack call trace of an segmentation fault. The first one 
  I posted was with glibc "libc6 232.ds1-10 (unstable)" on a debian 
linux server. This second seg fault was with glibc "libc6 2.3.2-9 
(testing)".
the seg fault again occured in libpthread.so.0.
I'll now try oldest available glibc "libc6 2.2.5-11.5". But I can't 
imagine it will help.
It seems that there is going something wrong with FB 1.5 SS on debian linux.
