Dear Sirs.
While under FreeBSD 4.6.2-pl2 Portland's PGI compiler 4.0 had no
problems compiling several numerical simulations, under FreeBSD 4.7-R
a simpel 'Abort trap' occurs!
The first suspect was the Linuxulator on a P4 machine with FreeBSD 4.7-R,
but logging into a PIII SMP machine showed up no problems. Compiling
there (also FBSD 4.7) and running the program showed no problem!
Then, after a few runs, also those systems on which the small Fortran
program seems to run showed up the same error, out of the blue!
Then I tried to compile the same small programm with the native FBSD 4.7
compiler! And I got the same problem!
Abort trap
This problem is not reproduceable. After a while I can compile it again,
and then not.
Doing a ktrace gives no glue, also truss, which gives:
truss dopptag
process exited before exec'ing
dopptag is a standard f77 program which runs well under Linux SuSE 8.1
and, if it compiles, runs well under FreeBSD.
but this early Abort trap seems to show up a serious error.
Borth, pgf90, pgf77 AND FreeBSD native f77 produces this error!
Please aske me for the Fortran code if you need the code to validate
this behaviour.
this is dmesg output of the failing system (but it fails also on all
othe machines, which have FreeBSD 4.7-RELEASE!):
