--- Comment #14 from Bernd Edlinger <bernd.edlinger at hotmail dot de> ---
One question though...
This depends on a special knowledge about "vfork",
but it seems that gcc does not honor -ffreestanding
correctly in this case, because:
gcc -ffreestanding pr71104-1.c
should not have crashed (before your patch, but it did).
