Fair enough - please go ahead with your fix.

I think that my patch should remain however, possibly with a changed error
message, as I am not a fan of calls to abort() inside a library.  In my
opinion a library call should never end up with a seg-fault if it is possible
to return to the caller with an error condition set.  Even for something that 
is never expected to happen.  

Cheers

PS. I was finally able to reproduce the problem, but only with a toolchain
configured for an i686-pc-inux-gnu target rather than x86_64-pc-linux-gnu.
