Should be fixed now, but I'll put this into the WAITING state pending
confirmation from the reporter that this patch really fixes the issue for him..

I confirm the compile-time improvements from the complete patch (2%
enable-checking, 0.8% disable-checking), but there's no improvement in SPEC (no
regression either).

It's become a libstdc++ test, but anyway: -O -fstrict-aliasing

inline Context_t context() {

There are no overlapping fields created from push_fields_onto_fieldstack, so my
pointing to PR22488 may be wrong.

That leaves aliasing and DCE.
The following statement connects to the initializing of the function pointer.
# SFT.78D.2952_55 = V_MAY_DEF SFT.78D.2952_31;
# VUSE D.2838_29;

The attached code (a md4 function, about 100 lines) takes many minutes
(apparently 100) to compile with gcc mainline 4.3 at -O3. At -O2, or with gcc
4.2, it takes below 1 second. 4.3.0 20070411 is OK, too. Memory requirement
stays very low.
The top of a profile with mainline looks like this:

I compiled the target i686-pc-cygwin, two times, with a long list of options.
One compilation used --with-included-gettext the other used
--without-included-gettext.
The --with-included-gettext version, make -i check reports:

ends up having to phi translate back through 1000's of other value handles.
But it should have already solved these, so i'm not sure

No DECL whose mangled name includes the name of an anonymous namespace should
be TREE_PUBLIC. That is the bug here.
There are no problems with typeinfo on systems where typeinfo is compared by

I get no ice or segfault on the original test case nor the one in Comment #7.
I do get what looks like some garbled text on the second test case:
Error: Procedure '#65533;,#65533;' in generic interface 'bar' at
With Dominique's fix so that the test case runs, I get failure.
Here is a slightly modified version to illustrate:
