Sure: I'd have tested that on Linux/x86_64 before submitting anyway.

What I've done is adding a couple of printf's all over
template <typename I, typename F> void foo (): before the #pragma omp
parallel for, before and after each assignement in the for loop, and
before and after the abort, every time casting the args to long long
resp. long double with matching format strings.  It I initialize i to 0
before the #pragma so I get comparable output, there's no difference in
output between i386-pc-solaris2.10 and sparc-sun-solaris2.11 except for
the abort.
