Nested functions depend on dynamic code generation on the stack.  If
your system manager arranged to disable the execution permission of
data/stack segments, gcc breaks.  It took me months to figure it out
when it happened to me: it was only when I tried to run Kaffe OpenVM
with JIT that I noticed there was something really weird going on, and
could identify the problem.

But the problem you're observing may obviously be anything else... :-)
