A bug report of Segmentation fault (core dumped)

[x0v0l]

Hey guys~ a Segmentation fault appeared when I applied TyPM on Linux kernel bc files. File names of all bc files of linux source code (Linux 6.6.12) are in bclist.txt. All things seemed fine when processing files and building call graph, but at last, the program got stuck for a long time and finally core dumped. Is it a bug of TyPM or simply a lack-of-memory issue? Because there are more than 500G memory available in the server environment where TyPM works, I think maybe it's a bug. The crash backtrace and the screenshot are attached below.

I meet a similar segmentation fault, have you fixed it?
