Hi Jason,

the problem is this ridiculously large value for the last vertex, and
the question is where it comes from. Unfortunately from the stacktrace I
cannot tell where it comes from. If you have time to spare on this,
could you try the following (I suggest in this order):
* Compile OC without optimizations enabled (-O0), and see if the crash
is still there. This should give us a bit more helpful stacktraces as
well, without those <value optimized out> labels at some places.
* In src/lib/StdMesh.cpp in line 1199, use std::sort instead of
StdMesh_tim_sort, and see if the crash is still there (just comment out
the timsort and comment in the std::sort).
* Run the whole thing in valgrind up to the point of the crash (I know
it's painful...), and show the valgrind error log. I'm only interested
in the memory errors, not the memory leak report. I suggest redirecting
the valgrind output to a file to make sure you don't lose anything.
Thanks and cheers,
Armin
The stacktrace would be a bit more helpful without optimizations in the
binary enabled.
