Description
x86_64 64bit platform, Linux 2.6.22, glibc 2.7, gcc 4.2.2, swig 1.3.31 (also
tested with swig 1.3.32rc1), subversion 1.4.5, perl 5.8.8
When trying to use git svnimport or perl Makefile.PL in SVK then segfault happens
in subversion bindings:
[arekm@carme-pld SVK-v2.0.2]$ gdb --args perl Makefile.PL
