The following program, compiled with “pgfortran -mcmodel=medium …” leads to a run-time error on Linux x86-64 when the array cannot be allocated.
allocatable i(:)
allocate(i(HUGE(1_8)),source=0,stat=j)
end
Not recommended that you use -mcmodel=medium, if you are
not statically allocating the arrays, as in
integer I(HUGE(I_8))
because every other object linked needs to be compiled
-mcmodel=medium.
But do add
-Mlarge_arrays
because you need 64-bit integer arithmetic to calculate array-index-to-offset calculations.
In either case, if you have the ‘stat’ argument, the allocation should fail and the stat should be set to a known value.
I have filed TPR 24942 to address this.
