I hit the jackpot on the first try! Building without netcdf support solved the IRIX problems. I've been using netcdf 3.4. Has anyone tried the 3.5b2 version?

Hi All, After working with Greg Gabra last week, we managed to eliminate the dictionary as the source of the memory corruption running samples on IRIX. I also tried upgrading to IRIX 6.5.7f to get a fix for a Motif library memory corruption problem, but this didn't solve it either. However, I think I've finally managed to isolate the problem and would like to toss it out here to see what you think. I made two copies of AutoColor.net and modified them as follows: In one copy, I specify the full pathname to the watermolecule.dx datafile in the Import module and in the second, gave "watermolecule.dx". (The original AutoColor.net only has "watermolecule" in the name field in Import.) Each of the two copies run perfectly while the original still dumps core when I try to rotate it! That sure suggests to me that the memory corruption is actually happening during the data importing process, in particular while trying to determine the datafile format if it's not specified. The problem could be in one of the import routines (in src/exec/dxmods) or it could be with the netcdf, cdf or hdf libraries. I'll try rebuilding DX a few times, eliminating a different data format library each time to see if I can narrow it down some more. Any other advise, or independent confirmations that this is causing trouble would be welcome. ********************************************************************* Alan M.
