OOMalloc
A library meant for testing application behavior in out-of-memory conditions with the use of LD_PRELOAD trick.
Requirements
- Linux
- glibc - the library contains some glibc-specific code. It will probably not work with alternative libc implementations.
Compiling
cmake . && make
Usage
# enable allocation logs
OOMALLOC_LOG=1 LD_PRELOAD=liboomalloc.so ./your-application
# make the 11th allocation return NULL
OOMALLOC_FAIL_AFTER=10 LD_PRELOAD=liboomalloc.so ./your-application
# make malloc/calloc/realloc fail when heap allocations exceed 10000 bytes
OOMALLOC_LIMIT_HEAP=10000 LD_PRELOAD=liboomalloc.so ./your-application
