Re: [Gc] Bug in GC_malloc_explicitly_typed_ignore_off_page()

[Ivan Maidanski]

Hi Reimer,

Thanks for reporting & fixing the bug.
I've applied your patch (https://github.com/ivmai/bdwgc/commit/13a88c0704d6f83ff97be0a246692e0e2da292f5) both to master and release-7_2 branches (https://github.com/ivmai/bdwgc).

Regarding GC_generic_malloc_ignore_off_page, again you are right - it is a companion for GC_generic_malloc and, thus, it is reasonable that it should have similar visibility. I've made it public today (only master branch) - https://github.com/ivmai/bdwgc/commit/7bd92c91f5712ff6723eb2479d0442cd6154a10e

Regards,
Ivan

it appears as though GC_malloc_explicitly_typed_ignore_off_page() has a

typo. Namely, it uses BYTES_TO_WORDS() instead of BYTES_TO_GRANULES() in

the else branch. When the result is then used with GRANULES_TO_WORDS()

to calculate an offset, that offset is incorrect.

I've attached a patch against 7.2d.

On a related note, is it intended that

GC_generic_malloc_ignore_off_page() is marked as GC_INNER instead of

GC_API and does not have a prototype in gc_mark.h?
