[daip] VTESS problems under g77 3.2.2

[rlaing at eso.org]

Dear AIPS group

I recently attempted to use VTESS under a version of 31DEC04 downloaded and
compiled on 2004 Jan 16 using g77/gcc 3.2.2 under Linux RH9. This failed
consistently on a number of datasets, giving 0 and NaN for step and gradient,
and always generating a flat image. Reverting to a VTESS.EXE compiled using
an older g77 under RH6.3 gave sensible results [I'll send fuller details if they
are of any use to you].

Would you recommend returning to gcc 2.95.3 or is there a known work-around for
3.2.2 (e.g. in a more recent incarnation of 31DEC04)?

Thanks

Robert
