Re: Tru64 Doldrums...

We were getting these SIGSEGV failures for an old Forms 6 executable and after a load of trussing, tracing and support collaboration we noticed that it was using an old Motif library supplied by Oracle and not the OS . Once we then sorted LD_LIBRARY_PATH to pick up the correct library first the problem was solved. We used the ldd command to examine the dynamic dependencies of the forms executable.

This was on Solaris, you may be having a similar problem.
