Comment 2

[Paul Bone [:pbone]]

This crash can occur when jemalloc is given a bad pointer. Most likely an interior pointer to a valid jemalloc object given that it already passed assertions that check that it is pointing to a valid chunk. And that the interior pointer points to a different page from the object itself. Eg:

---

void* good_pointer = malloc(PAGE_SIZE * 4);
void* bad_pointer = good_pointer + PAGE_SIZE;
malloc_usable_size(bad_pointer) // crash

Or a UAF:

---

void* old_pointer = malloc(PAGE_SIZE);
free(old_pointer); // Can merge adjacent free runs
void* new_pointer = malloc(PAGE_SIZE*4); // Could allocate a run such that old_pointer is an interior pointer.
malloc_usable_size(old_pointer) // crash

I'm going to punt this to the JS GC team in case they have any clues regarding the call site. But it could be anything, including heap corruption.
