comfirmed on gcc-9.0

Currently, I tested on gcc-9.0, I could reproduce the same there.

I found the crash function name differs this time, from the previous function
name, whereas the backtrack remains the same, So is this same bug?

Confirmed, it's very old ICE (4.8.0+).

Cleaned up test-case:

$ cat pr87118-2.c
struct {
  unsigned a: 7;
  unsigned b : 3;
} b;

void d() {}
void c() {
  __transaction_relaxed { d(b.b); }
}
