1222	ppsim segfaults under simtest	Sebastian Jester	Paul Price	"I build ppsim from this svn export:

{{{
svn export -r {2009-04-14} https://svn.pan-starrs.ifa.hawaii.edu/repo/ipp/trunk/ ./svn-20090414
}}}

I run simtest with 
{{{
 simtest.setup.basic
 simtest simtest_20090414 aida77 new
}}}

I get segfaults in simtest for all ppsim calls from simtest.mkimages line 41 and above, i.e. for FLAT and OBJECT frames:

{{{

Here's what happens when I run ppsim in gdb:

{{{
