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. > Can you get a coredump from the fault and see what the faulting > instruction was? 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. Regards, Sven
