Segfault when using ltdl #411

Closed kwharrigan closed 7 years ago

kwharrigan commented 8 years ago

I started a mailing list topic on this w/r to ImageMagick's "convert" crashing, which I've reduced down to a trivial test case involving use of libtool / ltdl. Apologize for the delay in getting this submitted.

@rohgarg suggested running with disable-alloc-plugin, and that works, so presumably the issue is in there somewhere.

Have a look at https://github.com/kwharrigan/dl_vs_ltdl. You can run make dmtcp_test and should get a segfault when trying to run the ./ltdl under dmtcp_launch

@kwharrigan: Sorry about the extremely long delay on this. I think we have a solution to this problem now. The PR #347 and a few other patches on top of that will address this issue.

Fixed via PRs #444 and #456.
