We are aware of an issue where the OnDemand Shell app is not functioning in Firefox 148.

cuda-gdb segmentation fault on startup

Resolution: 
Resolved

The CUDA debugger, cuda-gdb, can raise a segmentation fault immediately upon execution.  A workaround before executing cuda-gdb is to unload the xalt module, e.g.: 

module unload xalt

This issue affects most cuda modules on Pitzer and Owens.
