I discovered the bug as I tried to compile glibc inside the domU.
glibc's configure tries to compile a test program to determine the
sizeof the long datatype or something simple like that. So at least this
is another program that fails.

I did quick test, whether the empty program (just a main with return 0;
in it) segfaults - but it doesn't segfault. The moment I add a printf,
it segfaults again.

How do I do that?
Sorry for the stupid question, but unfortunatly this is beyond my
knowledge of the tooldchain :-(

I didn't find any automatically generated file.

  Sven
