Description

@DavisVaughan reports that the following hangs Ark:

debugonce(eval)

From what I can see, debugonce() drops in the debugger right away because it triggers srcref generation for the base namespace, and eval() is called by reparse_with_srcref(). Then something bad happens and hangs Ark.

Research direction

Reproduce the hang with debugonce(eval) in Ark, then trace the debugger entry and the reparse_with_srcref() call mentioned in the report. Determine where execution stops and confirm that the command completes without hanging after the fix.
