Confirm.
Valgrind shows:
Process terminating with default action of signal 8 (SIGFPE): dumping core
Integer divide by zero at address 0x40274EADB
at 0x4008C6: MAIN__ (ghfhgk.f90:15)
> Divide incorrectly extracted from WHERE block?
Yes and no. The compiler essentially transforms (as -fdump-tree-original shows)
WHERE (RDA < -15.0)
IDA = 1/NF0 + 2
ENDWHERE
into
TMP = 1/NF0 + 2
WHERE (RDA < -15.0)
IDA = TMP
ENDWHERE
which is the reason for the integer divide by zero and shows that moving
constant expressions out of a loop is not always a good idea.
