cuffdiff segfault

[Ichinichi]

cufflinks works, cuffcompare works. problem is with cuffdiff. entire pipeline is tophat/cufflinks. i've tried my reference gtf, the combined gtf, regenerating the sam files, my own local executable, our system level executable (both v0.8.1).

version: cufflinks-0.8.1

gdb says the segfault occurs on line 174 of gff.cpp:

173.  GffLine::GffLine(GffReader* reader, const char* l) {
174.  line=Gstrdup(l);

cmd:

~/cufflinks-0.8.1/src/cuffdiff combined.gtf inputs/vee.sam inputs/cee.sam
