recall

Profile memory on Unix systems using the LD_PRELOAD trick

Build

$ ./scripts/build.sh

Examples

Linux

$ export RECALL_BT_DISPLAY_INTERVAL=1
$ LD_PRELOAD=./build/librecall.so ./build/leak

macOS

$ export RECALL_BT_DISPLAY_INTERVAL=1
$ DYLD_INSERT_LIBRARIES=./build/librecall.dylib ./build/leak
