Oggetto: G77 160 MB memory allocation limit

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 cygwin1.dll

Simple programs compiled with -mno-cygwin flag may allocate up to 1920 MByte.

With the old 1.5.12 the usable size (2BG RAM machine) was 1536 MByte.

Why ???
