Segfault when OMNITRACE_USE_ROCTX is true #259

Closed gsitaram closed 1 year ago

I am using Omnitrace that is built with rocm-5.4.3. Build instructions from omnitrace documentation have been used. Setting OMNITRACE_USE_ROCTX=true in the config file results in a segfault when running a MPI process:

Backtrace (demangled):
[PID=1236084][TID=0][0/8] __restore_rt

[PID=1236084][TID=0][8/8] Jacobi_t::Jacobi_t(grid_t&, mesh_t&) +0x6e0

which disappears when I set disable OMNITRACE_USE_ROCTX in the cfg file.

Thanks for the fix, @jrmadsen!
