c++: fix ptrmemfunc template instantiation [PR101219]
r12-1804 ("cp: add support for per-location warning groups.") among other
things removed warning suppression from a few places including ptrmemfuncs.
This exposed a bug in warning detection code as a reference to missing
BINFO (it's intentionally missing for ptrmemfunc types):
crash_signal
gcc/toplev.c:328
perform_or_defer_access_check(tree_node*, tree_node*, tree_node*, int, access_failure_info*)
gcc/cp/semantics.c:490
finish_non_static_data_member(tree_node*, tree_node*, tree_node*)
gcc/cp/semantics.c:2208
...
The change special cases ptrmemfuncs in templace substitution by using
build_ptrmemfunc_access_expr() instead of finish_non_static_data_member().
gcc/cp/ChangeLog:
PR c++/101219
* pt.c (tsubst_copy_and_build): Use build_ptrmemfunc_access_expr
to construct ptrmemfunc expression instantiation.
gcc/testsuite/ChangeLog:
PR c++/101219
* g++.dg/warn/pr101219.C: New test.
