xrobau commented on ASTERISK-26242:
-----------------------------------

Oddly enough, that was with our 2.1.1 build of DPMA.  We noticed that a new version had been published, so we upgraded to 3.0.0, and this is now the backtrace.

Note that the actual stack frames are missing, because they've been stripped. It was really lucky that we happened to have a NON stripped version so we could find the issue straight away.
