Can confirm the crash.

Looks like this might just be a typo?
BMLoop *l is used here (and NULL) [and it looks like l was meant for another loop.... but I could be totally wrong here]

maybe like P824?

but leaving to @Howard Trickey (howardt) to decide.... mind having a look?

I too confirm the crash and will work on fixing it.

Indeed, it was a type for Loop variable. Thanks. Fixed now.
