debugging code linked to AMReX hangs

[tesari]

Hi,

I have AMReX build as a library in debug mode. When debugging my code, the debugger hangs at ‘New Thread …’:
…
Starting program: my_program
[New Thread 0x5307 of process 87690]

I am aware that I need to change the values of throw_exception and signal_handling, but I initialize MPI with

amrex::Initialize(glb::myComm);

and cannot figure out how to do that. Could you advise, please?

Thanks,
Ted

This might be a bug in gdb or macOS. https://apple.stackexchange.com/questions/420492/gdb-hangs-after-new-thread-on-macos. So probably no changes in amrex can help. If you want to disable signal handling and enable exception without using amrex::ParmParse, you can do

amrex::system::signal_handling = false;
amrex::system::error_handler = nullptr;
amrex::system::throw_exception = true;
