- Subject: [Patch, fortran/testsuite, committed] Fix test case on systems with 32bit pointers (PR 37399)
This fixes my previous test case, where
allocate(array(something_HUGE))
was used. The something_HUGE was a 64-bit variable which gets converted
to 32bit for systems with 32bit pointers.
As the variable overflows, an error is printed. There are two solutions:
(a) Using -fno-range-check, (b) comment the statement. I have decided to
do the latter (does not really matter, it is a compile-time check only).
I've committed the following patch as obvious. Thanks to HJ for finding it.
