>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.

Not known!
