            Bug ID: 32652
           Summary: Scudo-x86_64 quarantine.cpp fails
           Product: compiler-rt
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: compiler-rt
          Assignee: unassignedbugs at nondot.org
          Reporter: hfinkel at anl.gov
                CC: kcc at google.com, llvm-bugs at lists.llvm.org

This test fails on my build system (during a self-host check):

Scudo-x86_64 :: quarantine.cpp

/src/llvm/projects/compiler-rt/test/scudo/quarantine.cpp:29: int main(int, char
**): Assertion `__sanitizer_
get_current_allocated_bytes() > allocated_bytes' failed.

The problem is that, both before and after the call to malloc,
__sanitizer_get_current_allocated_bytes() returns 0. Thus, the assertion fails.

If I change the size allocated in the test to something more than (1U << 16),
(1U << 17) or (1U << 20) for example, then the test consistently passes.
