@yasuoka I have tried compiling your tool on ubuntu and ended with below issue. Is this tool developed for BSD Linux?

cc -fPIC -g -Wall -shared -o mleakdetect.so mleakdetect.c
mleakdetect.c:18:10: fatal error: sys/tree.h: No such file or directory
18 | #include <sys/tree.h>
| ^~~~~~~~~~~~
compilation terminated.
