Patch to fix the issue
I was unable to create a reproducer in C for the tests.
It seems the problem was actually in

I don't know if this helps, but I added a small Rust reproducer that can
trigger the segfault when compiled with rustc_codegen_gcc and the corresponding
GIMPLE for this Rust reproducer.

I might be able to soon create a reproducer, but for now, I can say it might be

inlined_call_event's ctor should probably assert that params
tree apparent_callee_fndecl,
tree apparent_caller_fndecl,
are both non-NULL, which might catch the

Reproducing that is going to be a challenge.
FWIW you can probably work around it via -fno-analyzer-undo-inlining.
For an inlined_call_event's m_apparent_caller_fndecl to be NULL, then when it
was created
