With the attached file. It will consume all available memory and crash.

Looks like this was caused by revision 61207. Checking that.

This is pretty common problem, when bootstrap itself is broken.

[llvmbot]

llvm-gcc bootstraps with 61206. With 61207 it fails at the attached testcase.

Feel free to revert it then.

This also breaks the Ada build (at a different point, not using
precompiled headers). The debug info stuff goes into an infinite
