Native.free cause crash in callback from C++ dll #1370

Closed lovelypp777 closed 3 years ago

lovelypp777 commented 3 years ago

My DLL defines a callback function named as mycallback DLL_API typedef void(mycallback)(void ptr, int userData); where ptr is a mallocated buf: ptr = (MyStructure*)malloc(sizeof(MyStructure));

in java, before return from mycallback, it calls Native.free to free the memory: Native.free(Memory.nativeValue(ptr));

when call Native.free，the vm is crashed.

my dll is a x64 which is developed us msvc 2019. java sdk version is jdk-8u301-windows-x64.

the following is the log file(hs_err_pid16904.log) generated:

This is not a QnA forum. Use the Google Group clearly referenced in the issue template:

When you ask, please prepare a self contained reproducer, that shows your problem. The google group should be used because there are other people that are willing to help and not just direct project committers.
