The general consensus is that there are bugs in it, but the overall performance is better than that of fortran v1.2. Bugs: o If an unformatted file of length >8k is created, the program should be created with -Bstatic option. o Because of a bug in the SunOS, use of TMPFS filesystems in v1.3 cause problems. Work-around is to apply the relevant OS patch. o Function statements sometime generate bad code. Feature: o Can not mix object codes of v1.2 and v1.3. General Comments: o Most people seemed to be quite pleased with v1.3.1 at patch level 2. The programs seem to run faster with this version of the compiler (will this change the Mflop rating of our computers? ;). o One can also run v1.2 with SunOS 4.1.x. One can just copy the old compiler to the new system; or reinstall, and when the installer fails, modify extract_unbundled in /usr/tmp/unbundled to include 4.1 in supported OS types, and run *this* installer script. o Sun is coming out with a new version of fortran compiler sometime in spring. Question to more knowledgeable readers: o While it is possible to combine old (OS4.0.3) c object codes with the new fortran, why is it not possible to combine v1.2 object codes? Or am I mistaken about compatibility with c object codes?
