Research direction
The issue names no files, tests, or entry points. Start by locating the pthread build configuration and dlmalloc lock setup, then trace how the libc allocator is exercised in threaded builds. Done means establishing whether locks are enabled there and adding or updating a test that verifies thread-safe allocator use.
