[PATCH v3] libstdc++: fix pointer type exception catch [PR105387]

[Jakob Hasse]

Hello,

two weeks ago I submitted the second version of the patch PR105387 for the bug 105387. Now I added a pointer-to-member exception test just to make sure that it doesn't break in case RTTI is enabled. The test is disabled if RTTI is disabled. I didn't receive any feedback so far regarding the second version of the patch. Is there any issue preventing acceptance?

I ran the conformance tests on libstdc++v3 by running
make -j 18 check RUNTESTFLAGS=conformance.exp

Results for the current version (only difference is the added pointer-to-member test):

Without RTTI before applying patch:
=== libstdc++ Summary ===

# of expected passes 14560
# of unexpected failures 5
# of expected failures 95
# of unsupported tests 702

Without RTTI after applying patch:
=== libstdc++ Summary ===

# of expected passes 14562
# of unexpected failures 5
# of expected failures 95
# of unsupported tests 703

With RTTI before applying patch:
=== libstdc++ Summary ===

# of expected passes 14598
# of unexpected failures 2
# of expected failures 95
# of unsupported tests 683

With RTTI after applying patch:
=== libstdc++ Summary ===

# of expected passes 14602
# of unexpected failures 2
# of expected failures 95
# of unsupported tests 683

Given that the pointer-to-member test is disabled when RTTI is disabled, the results look logical to me.
