That must be a different problem, perhaps 98333.

I got reports for this issue for the gcc-10 branch as well. Please could you
consider a backport?

c++: Crash when deducing template arguments [PR98659]

maybe_instantiate_noexcept doesn't expect to see error_mark_node, but
the new callsite I introduced in r11-6476 can pass error_mark_node to
it.  So cope.

gcc/cp/ChangeLog:

PR c++/98659
* pt.c (maybe_instantiate_noexcept): Return false if FN is
error_mark_node.

gcc/testsuite/ChangeLog:

PR c++/98659
* g++.dg/template/deduce8.C: New test.

I see this problem when compiling package nheko.

I will try to produce another test case.
