Charm++ parallel programming system

Just to make sure, you have fully recompiled your code with the upgraded version of Charm++? The system offers no ABI preservation from one version to the next.

Hi folks,

Updating from Charm++ v6.7.1 to 6.8.2 breaks executables with the runtime error
in the subject. Only with the gnu compiler suite, consistently with version 5,
6, and 7. Intel and clang are fine.

I wonder if this has anything to do with the following feature, introduced in
6.8.0:

"Charm++ programs can now define their own main() function, rather than using a
generated implementation from a mainmodule/mainchare combination. This extends
the existing Charm++/MPI interoperation feature."

Could some point me to how I can go about diagnosing and/or fixing this problem?

Thanks,
Jozsef
