For analysis: you can disable all the warnings, and therefore you will get only error messages. For simulation: you can also disable asserts. Does that help ?

There is -Wall and -Wno-all to enable/disable all the warnings. For assertions, maybe we can add a new flag to silent them until a level.

I fear we need an MWE or a reproducer: a set of files and instructions to reproduce the crash from the set of files.

No, I haven't received anything. Please, use the github web interface to attach your files.

Yes, I got it. But I need the sources; the object files are useless.

The P1 is an automatic given name to an anonymous process. If you cannot give the sources, you should create a reproducer: remove as much as possible from the existing...
