Unfortunately, I have had another crash during testing. I was not able to capture the core, but I did get this log:
Feb 28 03:35:22 [359] CRITICAL:core:qm_debug_frag: qm_*: prev. fragm. tail overwritten(c0c0c0c0c0c0c020, abcdefedabcdefed)[0x7fa6cd6c46b8:0x7fa6cd6c46f0] (del_uri_param, checks.c:242)! Feb 28 03:35:23 [353] INFO:core:handle_sigs: child process 359 exited by a signal 6 I am making adjustments to be able to collect the core if the crash occurs again.

When I removed the quotes around the regexp used in re.subst the crash did not occur.

However I am now seeing a different crash, but it seems to still be related to regexp.

And I’m not sure what the “string too short” error is either or why the regexp could not be compiled. It looks valid to me.

It’s just a return statement. I can send you the file off-list if you’d like. I do use the $DLG_dir in my script in a few places, but the only one this crash would have hit is in some logging.
