>Running gcc on input file from an attachment resulting in segmentation fault

The file didn't attach, maybe it was too big. Can you try to compress it and
attach that?

This is a won't fix stitutation. 

You have & on a type repeated 237,679 times. 

With a recusive decent compiler, you run out of stack space with that many
times.

....

Don't do that many times and you won't run into the stack overflow.
There is not much that can be done and the number of references types can be
done by the defualt stack size over 1000.
Any reasonable program will be able to compile.
Basically doctor it hurts when I do this, doctor: don't do that then.

I am fuzzing gcc to improve its quality. If it is not interesting crash, then
ok. Thanks

By the way, there is one more file (attached 0.cpp.gz).
gcc-9 0.cpp is processed but gcc-12 0.cpp - segfault. With extension .c its ok

Again this is just a limitation in the stack size.

Try doing:
ulimit -s unlimited

and you will most likely see they both work.
We could change the parser not to be as recusive function calls here but this
code is still not even reasonible by machine generated sense.
