Re: Thread::Queue dies in debugger, runs without debugger

[stevieb]

From perldebug:

perl -dt threaded_program_name

Debug a given program using threads (experimental).

So essentially, instead of running with perl -d, try running with perl -dt.

The 5.26 doc states that it's experimental, but my perldelta foo is failing this morning, so I can't figure out what version this feature was introduced. So worst case, you'll need a 5.26.x version of perl for this to work (hopefully I'll find the actual release, or someone else will).

perldebug 5.8.9 "Calling the debugger" lists -dt, but perldebug 5.8.8 doesn't even have that section -- though that may relate more to perl589delta "Changes to Existing Documentation" than that being when the -dt feature was added. But that means that "experimental feature" goes back at least as far as 5.8.9.

Holy crap, no wonder I couldn't find it. Good thing I didn't say "it's experimental, so it shouldn't have been in core for overly long" like I was going to! (I didn't, because I fully remember the whole smartmach fiasco, which iirc, is still kind of ongoing).

Thanks for digging, pryrt!
