Here's what Jakub Jelinek wrote in the RH bugzilla:

So that explains why including perl.h is relevant. Would you like to
try modifying your copy of pthread.h to confirm it's the same situation
on Ubuntu?
It's probably pure luck that my no-palloc patch dodges the problem, but
anyway it seems like a good enough work-around until the glibc issue is
fixed. I'll go ahead and back-patch that.
