Changed paths: M Source/bmalloc/bmalloc/DebugHeap.cpp Log Message: ----------- Cherry-pick 260115@main (397fe12d87a4). https://bugs.webkit.org/show_bug.cgi?id=252053 bmalloc DebugHeap should not crash in low-memory conditions on Linux https://bugs.webkit.org/show_bug.cgi?id=252053 Reviewed by Yusuke Suzuki. `posix_memalign` may not initialize the result pointer if it fails on Linux [1]. If we don't initialize the result ourselves, this manifests as later segfaults/bus errors/bizarre behavior as we get a completely bogus result that can point basically anywhere.
