I was trying to upgrade my compiler from Forte 6.0 (yikes) to Studio 11. In
the midst of this we installed various patches including 109147-40. We haven't
completed the switch to Studio 11, but now applications built with the Forte
6.0 compiler crash. For example, the tcl-8.4.2 "load" command crashes in a
function where it's calling dlopen. The stack shows a crash in strlen, but the
code seems right, has been working for years, and as soon as I revert the patch
to 109147-34 and rebuild one .o file and the .so, the application works.
I can provide a short script that recompiles just the one file and crashes.
Here is what it looks like when it works on machine guaraldi:
guaraldi:~/build/rel50/src/vendor/tcl/tcl8.4.2/unix $ ./doit

And here is the same script failing on desprez:
