[Bug objc++/42156] New: Hundreds of objc++ testsuite regressions

[ghazi at gcc dot gnu dot org]

Sometime between mainline revision 154353:
http://gcc.gnu.org/ml/gcc-testresults/2009-11/msg01929.html

and 154391:
http://gcc.gnu.org/ml/gcc-testresults/2009-11/msg01929.html

I'm getting massive numbers of objc++ testsuite regressions.

------- Comment #5 from jakub at gcc dot gnu dot org  2009-11-26 09:42 -------
The problem seems to be the new set_underlying_type call called from
build_self_reference.  Apparently the objc-act.c expects that type variants at
that point are only created for some other purpose (don't know objc, so have no
idea for what), and that they have TYPE_OBJC_INFO allocated, which is not the
case for these self reference variants.

Created an attachment (id=19152)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=19152&action=view)
gcc45-pr42156.patch

Untested patch.  I'm not familiary with ObjC/ObjC++, so have no idea whether it
is the right fix or not.

------- Comment #7 from howarth at nitro dot med dot uc dot edu  2009-11-26 19:29 -------
This patch on x86_64-apple-darwin10 returns the obj-c++ testsuite results back
to their previous results of...

                === obj-c++ Summary ===

# of expected passes            398
# of unexpected failures        52
# of unexpected successes       3
# of expected failures          15
# of unresolved testcases       1
# of unsupported tests          1

so it seems to be working fine.
