System: FreeBSD mail.physik.uni-mainz.de 4.7-RELEASE FreeBSD 4.7-RELEASE #3: Tue Oct

>Description:
Compiling numerical software with f77 from gcc-2.95.4/FreeBSD 4.7-RELEASE
results
in a unusable binariy image causing immediately 'Abort trap' after call. Same
problem
occurs compiling this piece of standard f77 code with PGI pgf90 or pgf77 under
Linuxulator, linux_base 7.1-1 as newly installed after installation of FreeBSD
4.7-R.
Using native f77 and gdb shows an immediately abort of the binary image.
Courios is the following observation: 30 minutes before the faulty behaviour,
the compilation AND execution produces the expected results. After that
this error occurs.
In the past we had the same problem with another small program which compiled
and
executed in the meanwhile. Before I was told to check what's wrong with the
reapetedly occurence of this strange behaviour I executed the binary from the
same NFS location on another system - with success! 10 minutes later on the
same
system I got the same error (Abort trap). this behaviour is more than strange!
>How-To-Repeat:
Can't be repeated, it seems to be weird what's going on. We couldn't reproduce
the problem due to the fact that under exactly the same conditions both results
were different.
We tried the faulty binary on another system - with success (also FreeBSD 4.7,
the same brand). After about 10 minutes, the same images showed up the same
behaviour.
>Fix:
Not known!
