It would be nice to have an intrinsic function to generate a user-requested
backtrace, like ifort's TRACEBACKQQ. Of course this would be a non-standard
extension, but a useful one which many other compilers also provide.
There has already been some discussion on this in PR30498, with suggested
workarounds like producing an FPE with "1.0/0.0" or calling 'kill' via
ISO_C_BINDING to generate a backtrace. But these of course terminate the
program.
For debugging purposes it can be helpful to generate a backtrace at some point
while keeping the program running, which is what e.g. TRACEBACKQQ does.
