I'm running PennCNV on a CentOS cluster with Perl 5.10.1 and I keep getting a segmentation fault error. Even with the example scripts for detect_cnv.pl

I tried using perlbrew and downloaded Perl 5.8.8 and explicity defined it in the she-bang line. Still same segmenatation fault.

Running make in the kext directory works without any errors. I tried PennCNV versions 1.0.2 and 1.0.3 on two different clusters (CentOS same version of Perl) and keep getting a segfault

What do?

../detect_cnv.pl -test -hmm example.hmm -pfb example.pfb -log ex3.log -out ex3.rawcnv  -conf -list inputlist

After looking at the code (C/XS and dependent on version-specific Perl API), I don't think anyone other than the author would be able to help with this issue. I would file an issue on github

I got the same problem with perl 5.14.2 on CentOS. We managed to make it work after we rebuild it with gcc44 4.4.7 (compatibility compiler instead of default gcc 4.8.5) (https://github.com/WGLab/PennCNV/issues/9)
