I can confirm for the master branch ( 3.7.1-alpha.8497793.unofficial )
Segmentation fault (core dumped)
No such problem on stable branch, and not yet either on my two branches.
So, it's new, it's fresh... (less than a year old)
traced to se.resize()
void mkfree(GenericSpline * sp, SplineEntryList::size_type i)
{
SplineEntryList::size_type j;
SplineEntryList& se = sp->SplineEntries;
se.resize(se.size()+1);
for (j=sp->SplineEntries.size()-1; j>i; j--)
se[j] = se[j-1];
}
But it might be due to a previous memory corruption because the
segfault is due to malloc.c, a code that is safe as long as memory is
not corrupted.
I would bet for, somewhere else, a write out of allocated area.
