[Bug libc/7066] Probable buffer overrun in strtold()

[nix at esperi dot org dot uk]

It's using the same compile line that glibc's 'make check' uses, which 
passes -std=gnu99 (IIRC: I don't have a build tree at the right point to verify 
this right now).

The original testcase in glibc calls strtold() with many different inputs: only 
this one crashes under -fstack-protector-all, and the corrupted stack is not in 
the testing function but within glibc itself. So I don't see how e.g. pointer 
width differences (not applicable on x86-32 anyway as far as I can see) could 
cause a problem. It's not as if this is a varargs function on AIX or something.
