Had some more time today.  So far I can't see a difference between the
--disable-alloca flag and not.

It's not actually omnicpp that segfaults, it seems it's python that
segfaults inside the _omniidlmodule.so.4.1 extension module (_omniidl
in python).  So far I have no idea why, it segfaults as soon as it
tries to enter void Prefix::newFile() in
src/tool/omniidl/cxx/idlrepoId.cc.  It doesn't even get to the first
statement of that function.  All I can imagine right now is that
somehow something on the stack goes wrong, but I have no idea how we
can have any influence on that.

I haven't really got much experience with this sort of problem, doing
most of my programming in pure python these days.  But I'll keep
digging around.
