Okay. This fails, too. I found one bug. The pdf code does a
	debug_printf("%ld %s\n", off_t, string);
the off_t uses two registers but according to the %ld modifier printf
uses only one. It uses the second register for printf which is however
part of the number and dereferencing it leads to the segfault we see.

I have a fix for that, the suite still fails, will investigate later
more…
