Fix locking region in sjlit_malloc_exec #244

Closed lbonn closed 7 months ago

lbonn commented 7 months ago

The locked section needs to extend until we are done modifying internal block offsets and sizes, otherwise we risk running into data corruption in a multi-threaded context.

This bug was introduced in 7de0fee9a7376b33e31a3903487cd9933da3a606
