Hi all,
I'm upgrading v8 from 10.8.154 to 12.4.254.
I found that if there's FunctionTemplate in the JavaScript, my program will
crash during v8::compile().
The crash is raised by my custom malloc/free function with some checking
mechanism.
The functions are working on the 10.8.154 but failing on 12.4.254.
I've checked the memory related functions in src/base/platform/memory.h
have been overridden by my custom ones.
I've also scanned through Zone related code diff between the 2 version but
found nothing suspicious.
Want to know if there's any other memory manipulation modified between the
2 versions.
