Richard's reorg of profiling to SSA uncovered some of issues with pure&const
functions that are fixed in the current mainline. Can you, please, check if
that solves your problem?

trying to build python 3.2~rc1, I run into:

I get (with the just built python (built with -fprofile-generate):

build-static$ ./python
XXX lineno: 1101, opcode: 0
Fatal Python error: Py_Initialize: Unable to get the locale encoding
Traceback (most recent call last):
  File
"/home/packages/python/3.2/python3.2-3.2~rc1/build-static/../Lib/encodings/__init__.py",
line 31, in <module>
XXX lineno: 39, opcode: 0
Aborted

The build is ok with the normal build.

hmm, can't set the status back to NEW, just to RESOLVED. ...

a normal build of 3.2rc1 succeeds with trunk r169142 and the proposed fix for
PR47271.

the profiled build still fails with:

You have to use your gcc account (I think).

I don't think this is a regression now as we never had good thread support for
gcov/profiling.  That is we don't do atomic adds for the profiling.

seen with a profiled build (make profile-opt

i486-linux-gnu. Using pybench as the PROFILE_TASK doesn't show this bug). Seen
PR22471, but this one was reported long ago. What other information should be
