ncmpcpp dumps core when fetching lyrics

eurydice
ktrace(1) suggests to me that it's a pathname issue based on this line:

33399 ncmpcpp  NAMI  "/home/ashlen/.config/ncmpcpp/lyrics//Porcupine
Tree - Arriving Somewhere But Not Here.txt"


Issuing

$ mv ~/.config/ncmpcpp{,.bak}

doesn't do anything to fix the issue, so it doesn't seem to be
a problem caused by my configs.


ktrace.out can be made available upon request. I didn't include it
because it's quite long.

First thing to look for when there's a core dump is to see if you can
get a useful backtrace. How does the output look from this?

pkg_add gdb
egdb ncmpcpp ncmpcpp.core
bt

If the lines output from "bt" don't have function names in,
rebuild ncmpcpp with "make clean; DEBUG=-g make repackage reinstall"
and try again.

Been like that for years on all installations here. Never taken time to
investigate, so thanks for the initiative.

Does rebuild suggestion still apply based on gdb output above?

Sorry Stuart, I think I accidentally replied to you directly the first
time I sent this. I'm still getting used to neomutt.

Hey, thanks for the prompt reply and for explaining what I needed to
do. Out of curiosity, why did you want me to install gdb as opposed to
using the version included in the base system? I did so, yet am unaware
of the difference between them.

Here's the output from egdb after recompiling:
