Description
When launching my program from Nvidia Nsight Compute, Module::load_from_string (deprecated) appears to work fine, but Module::from_ptx_cstr with an empty options list segfaults. I also tried Default::default() as the options list with the same outcome.

Research direction
Start by reproducing the crash when launching through Nvidia Nsight Compute, comparing Module::from_ptx_cstr with the deprecated Module::load_from_string and both options-list forms. Trace the from_ptx_cstr entry point and determine why the empty or default options path segfaults in that environment. Done means the issue no longer reproduces under Nsight Compute while the existing loading behavior remains intact.
