// FIXME: This test infinite loops on darwin because it crashes
// printing a stack trace repeatedly
UNSUPPORTED: darwin
// Verifies lib/fuzzer/scripts/unbalanced_allocs.py script

[libFuzzer] [NFC] Prefix all run lines with %run This patch does not do anything, but paves the way for future changes, where %run command will be expanded into a script performing the testing on device. Differential Revision: https://reviews.llvm.org/D46553 llvm-svn: 332144
