The case in that PR used to ICE until commit f04dc89.
Interesting, I don't remember expecting that patch to change behavior at
all.
BTW, it looks like your recent commits and emails have had
non-conventional subject lines; see
https://gcc.gnu.org/contribute.html#patches for more guidance.
For instance, the subject for this patch could be
c++: add testcase for PR103338
OK with that adjustment.
This patch simply adds
the case to the testsuite.
Successfully tested on x86_64-pc-linux-gnu.
PR c++/1033388

* g++.dg/parse/crash73.C: New test.
