[Bug c++/25383] New: Crash when using certain function pointer in template -- but presence of another function will avoid the crash

This example, as is, will cause:

blah.cpp: In function 'void Load() [with T = Blah, T* (* LoadFunction)() =
Blah::Create]':
blah.cpp:24:   instantiated from here
blah.cpp:13: internal compiler error: in build_call, at cp/call.c:323

The command is `g++ -c blah.cpp -save-temps`

`gcc -v` produces

Source file (with a function that, if uncommented, prevents the crash)

For some reason, when the commented-out function
"WhenThisFunctionIsUncommentedGCCDoesNotCrash" is uncommented, no crash occurs.
