Hi, libio enabled glibc, gcc 3.0, static binaries die in _hurd_stack_setup at start up time. I think the code is gcc generated, probably for the vararg.
Here is the relevant debug info. I am not too familiar with that code gcc generates for what type of function invocation etc. Maybe the vararg requires some setup on the stack in static-start.S? Thanks, Marcus Program received signal EXC_BAD_ACCESS, Could not access memory. 0x0804849b in _hurd_stack_setup (argc=0) at ../sysdeps/mach/hurd/i386/init-first.c:317 317 in ../sysdeps/mach/hurd/i386/init-first.c (gdb) quit The program is running.
