I've tried to find the steps to reproduce the same problem,
but it's very difficult to artificially manipulate GC and memory allocation related to the system.

Concurrently I've been analyzing the crash already occurred.
It tells me that there were many abandoned addresses in the register file.

Do you have ideas about the possibility that unnecessary addresses or values remain in the register file?

The register file grows while processing in JIT code without shrink.
I cannot find any shrink in JIT code as I've looked into it.
If it just grows, there would be many unnecessary things after one of the callframes is done in JIT code.
At last those would affect GC works.

Any comment, advice, and feedback welcomed.
