Pat says he got this failure once. Then he rebuild and reinstalled
everything and the failure went away, so he blamed bad interactions
with the make install target for it. So we should exclude this as
a possible reason.

Ignoring that we may not properly protect calls to libltdl for a minute,
the failure for you occurred even in the single-threaded case, did it not?
Does libltdl use any signals for itself?

What bad interactions do you think can happen?
