color/regex.c:314:5: runtime error: store to null pointer of type 'struct RegexColor *' about neomutt HOT 4 CLOSED

I have the same issue and I can trigger it reliably with the following:

$ cat ~/.muttrc
mono index bold ~N
mono index bold ~F
mono index bold ~T
mono index bold ~D
$ neomutt -D
color/regex.c:314:5: runtime error: store to null pointer of type 'struct RegexColor *'

from neomutt.

argh! the bloody mono command again.
Thanks!

I have a fix for this, but I haven't merged it yet.
I'll do so later today.
I plan to make a new release late next week.

color/regex.c:314:5: runtime error: store to null pointer of type 'struct RegexColor *'

"runtime error"? in C? That's weird.

The line it refers to is adding a new color command that takes a regex, e.g. color body.

Looking at the rest of the function, I can't see how either rcl or rcol could be NULL -- they've both already been dereferenced.

If NeoMutt crashed, did your OS create a 'coredump' file?
Haven't found.

If your distro is using systemd, then you can use coredumpctl to get a coredump / debug.
e.g.

coredumpctl debug neomutt

In the debugger, you can use the command: bt to get a backtrace.

When is this happening?
Immediately on startup -- e.g. when it's reading config -- or later whilst running?

How often have you managed to trigger it?

Can you post your color config?
Especially any color commands that take a regex.

Thanks

Colour fixed merged in f9c11d6.
