The test is one of mine. I will check over my notes and come up with a fix. I'm running the Fortran 77 code in gcc-testsuite-3.3.tar.bz2 through g95 and I've found that 20000601-2.f contains illegal code for Fortran 95 and probably Fortran 77. I don't have the Fortran 77 standard handy, but I believe the code is illegal; yet g77 compiles the code without warning or error. kargl[303] f77 -v -c 20000601-2.f Using built-in specs.

I have looked over my notes on this. A function call was needed to trigger the bug, and I used MAX(). Any other function call should be OK. I tried to rebuild a mainline g77 from 20010118 to check this, but couldn't bootstrap. I did build a version from 20010110, but the original and modified tests both passed (although the bug was still present if I complied the LAPACK file sgbtrf.f). 2003-05-27 David Billinghurst (David.Billinghurst@riotinto.com) PR fortran/10965 * g77.f-torture/compile/20000601-2.f: Fix non-standard code.
