I'm facing a bit of a weird issue here.

I'm working on a UEFI shell app, which, for some reason, hangs on exit, and by that I mean when I'm returning the final status from ShellAppMain.

ie: 

INTN EFIAPI ShellAppMain( IN UINTN Argc, IN CHAR16 **Argv)

{

EFI_STATUS status;

...

return status;

}

Looking through other examples, all other shell apps do exactly the same thing, yet mine hangs every time without fail.

I suspect it might have something to do with memory that was not freed, but that is just a suspicion for now as I had it exiting properly not that long ago.

Question here is, how can I figure out what is going on?

Are there any code analysis tools I could try?

Normally I would use something like valgrind, but I am not sure anything like it exists for UEFI shell.

Appreciate any help.

Thank you
