--- Comment #42 from Dominik Vogt <vogt at linux dot vnet.ibm.com> ---
With glibc-2.18 and the various patches, the following tets fail:

-m31:
 * deep-stack-uaf-1.C

-m64:
 * null-deref-1.c
 * deep-stack-uaf-1.C
 * overflow-vec-1.c
 * overflow-vec-2.c
 * float-cast-overflow-10.c

I.e. the same as with glibc-2.23.  At least this part of the problems is
solved.
