--- Comment #1 from Jérôme Richard <jeromerichard111 at msn dot com> ---
It is worth noting that if OMP_DISPLAY_AFFINITY is set to TRUE, the runtime do
not print the affinity when the issue occur (and vice-versa: the value is
printed when no problem happend).
A deeper analysis shows that it seems to comes from the function
gomp_team_start not being called (in libgomp/team.c), itself due to
GOMP_parallel not being called...
