Description
Running UnitTester on x86_64 crashes in BApplication::QuitTest4 with a segment violation. Debug report attached.
The location of the actual crash varies between (at least) insert_chunk and hoardUnsbrk in arch-specific.cpp but the root cause seems to always be corruption of the heap's free-chunk list, sFreeChunks, possibly due to the (lack of) locking the unit test performs.
Note this test runs fine on x86_gcc2, so the problem is something x86_64-specific.

To debug memory allocation problems, you can use LD_PRELOAD=/system/lib/libroot_debug.so ./program. This replaces libroot with a version using a slower version of malloc that takes care of erasing freed blocks, and other protection measures, and can detect some errors earlier and closer to the point where they happen.
