Turns out it was my $SIG{__DIE__} handler which was causing the problem.
I added a handler to inflate uncaught errors into an object exception,
so it could give me a nice stack trace.
>From the perlvar POD:
__DIE__ /__WARN__ handlers are very special in one respect: they may be
called to report (probable) errors found by the parser. In such a case
the parser may be in inconsistent state, so any attempt to evaluate Perl
code from such a handler will probably result in a segfault. This means
that warnings or errors that result from parsing Perl should be used
with extreme caution...
So by using:
local $SIG{__DIE__};
before requiring modules, this issue has been sorted out.
thanks to all who gave advice.
