Starting from 1.5.13 (14 and 15 subversions are the same) I experienced
all FOTRAN written programs using large arrays to crash.
No error message, just exit.
After investigation (WEB/mailing list) and testing programs I discovered
and verified that a new near 160 MByte allocation limit is induced by
Simple programs compiled with -mno-cygwin flag may allocate up to 1920
With the old 1.5.12 the usable size (2BG RAM machine) was 1536 MByte.
Nobody knows. Something changed. Perhaps in cygwin. Then again, have
you also installed XP SP2 in the period since 1.5.12? That caused massive
disturbances to process memory map space because M$ rebased all the dlls in
the whole world.
I don't think XP SP2 is relevant, as I have this problem on Windows 2000.
It's interesting to have this pinned down to the transition from 1.5.12
to 1.5.13. I have half a mind (but only half) to try and verify this.
