Not that easily.

If the bug you are looking at generates an internal compiler error
(ICE), then you have a good starting point.  Run the compiler under
GDB from the GCC build directory and it will use a .gdbinit script
that will set breakpoints at useful functions.  When the ICE occurs,
you can get a stack backtrace and start from there.

The ChangeLog entries frequently cite the PR number that the patch
fixes.
