Yes, thats true. Actually, there are even more users possible with
recent kernels.

There are significant differences in glibc between these releases. While
I had no problem with glibc-2.2.2 of SLES7, there was the same error in
"ex17" for glibc-2.2.4. 

Fortunately, this is a trivial one: ex17 is just a test program, which
tries to allocate a 1MB big stack. This simple patch will cure it:

The problem for SLES7 I cannot reproduce. But I can send you my complete
patch against the released version in PM.
