I tend to do something like
git log release/2.17.13-1..release/2.17.14-1
for "problem occured between x and y" to look for a likely candidate
based on the commit message, and I just did that. Tell you what: easily
a third or more of all commits could be responsible.
There are two things for circling the problem: one is "git bisect" to
figure out the commit introducing the segfault. If nothing else, we can
then revert the commit until figuring out the problem. The other is
post-mortem-debugging the segfault to figure out the code where things
go wrong.
Either will require a developer being able to reproduce the problem.
Try reducing a file of yours to a point where the segfault still occurs
but most of the content could get thrown out.
