# Tests break on windows unless exe extension is used (because there are periods
# in expansion of %t, the string after the period is interpreted as the file
# extension, so each compilation will clobber the previous one's lib and exp
# files causing symbolization to break).

SUMMARY: libFuzzer: out-of-memory

RUN: not %run %t-OutOfMemorySingleLargeMallocTest.exe -rss_limit_mb=300    2>&1 | FileCheck %s --check-prefix=SINGLE_LARGE_MALLOC
RUN: not %run %t-OutOfMemorySingleLargeMallocTest.exe -malloc_limit_mb=300 2>&1 | FileCheck %s --check-prefix=SINGLE_LARGE_MALLOC
RUN: not %run %t-OutOfMemorySingleLargeMallocTest.exe -rss_limit_mb=1000 -malloc_limit_mb=300 2>&1 | FileCheck %s --check-prefix=SINGLE_LARGE_MALLOC

We used to check for "out-of-memory (malloc(53{{.*}}))", but that would fail
sometimes, so now we accept any OOM message.

SINGLE_LARGE_MALLOC: libFuzzer: out-of-memory

# Check that -rss_limit_mb=0 means no limit.
