This sounds like the same problem I reported last year (on Solaris/SPARC); 
it's issue #603:

    https://github.com/parrot/parrot/issues/603

There's a hacky patch that works around the problem included with that 
issue.  Unfortunately, the github migration messed up the patch so it no 
longer applies, but there should be a link back to the old version on Trac 
which might apply, unless Parrot has changed too much in the meantime.

I suspect a bisect will not be helpful.  At least when I tried to bisect 
to diagnose issue 603, there were too many broken intermediate versions.
