Author: Roger Sayle <roger@nextmovesoftware.com>
Date: Wed Mar 16 23:20:34 2022 +0000
PR c/98198: ICE-on-invalid-code error recovery.
This is Christophe Lyon's fix to PR c/98198, an ICE-on-invalid-code
regression affecting mainline, and a suitable testcase.
Tested on x86_64-pc-linux-gnu with make bootstrap and make -k check
with no new failures. Ok for mainline?
