5923	closure_flags[]  contains wrong _BTM data (whether the layout is bitmap or pointer first)	nomeata		"After reading through source:rts/sm/Scav.c I find that among the objects on the heap, only closures of type PAP and AP have a bitmap to describe the pointer/data-layout of their payload, all others use the pointers-first-convention.

This is in contrast to what source:rts/ClosureFlags.c claims in closure_flags[] , which says that all THUNK_-types have this bit set.

It seems that the bitmap data in closure_flags[] is not used anywhere, so this is but a source of confusion."	bug	closed	normal		Compiler	7.4.1	fixed		pho@…	Unknown/Multiple	Unknown/Multiple	Other	Unknown
