Thanks for pointing this out.  Since I'm using a gcc with those
patches (without releasing it) and a patch mathinline header,
everything's fine for me.

could lead to similiar results as you noticed since the stack could be
overrun.

Ok, let's close this since both ends (gcc and glibc) are fixed now.
