Hi Paulo,

Yes, this certainly fixes my segfault.

Valgrind complains a little - although I am not sure if this is important (I
am very new to the helgrind tool).  In case it is useful, I attach the
output I get,

So the line numbers are meaningful, I include my modified par_loop.h and my
test file.


Here is my g++ -v

Using built-in specs.

Many thanks for your assistance with this. My gratitude to the FSF grows
daily.
