No options. With follow child (-f) it looks similar tho;

Looks like cgal and eigen are different, so i'll try downgrading cgal and
upgrading eigen.

Re: [gentoo-user] openscad seg fault

[Godzil]

If it's build using debug options, looking with GDB where it fail would be much 
more useful than a random dependency graph.

It's intriguing that it default just after doing a mmap:

mmap(NULL, 4096, PROT_READ|PROT_WRITE|PROT_EXEC, MAP_PRIVATE|MAP_ANONYMOUS, -1, 
0) = 0x7f50a7949000


What options did you pass to strace to get this log? Have you set the "follow 
child" option?

I can open the program ok, but when I click on New it seg faults. Strace of
its death below.

I tried recompiling it and all its immediate dependencies. How do i
troubleshoot this?
