New submission from Anselm Kruis: Version: 2.7.4 (and any prior 2.7-version. not tested with 3.x) Compiler: VS 2008 Professional
If I compile Python using the batch > PCbuild\build_pgo.bat -2 Visual Studio fails to correctly collect profile information for the project "python27.dll". As a result, no real optimisation takes place. The command "build_pgo.bat -2" runs the full test suite (..\lib\test\regrtest.py) to collect profile data. Experiments show, that several test cases (i.e. test_os and test_subprocess) break the collection of profile data. Probably the failure is related to the creation of sub-processes. I consider it a Visual Studio bug. To work around this issue I created a list of good test cases and patched build_pgo.bat to run only the tests from this list. ---------- components: Build, Windows files: build_pgo-2.patch keywords: patch messages: 186322 nosy: akruis priority: normal severity: normal status: open title: Windows: build with "build_pgo.bat -2" fails to optimize python.dll type: compile error versions: Python 2.7 Added file: http://bugs.python.org/file29739/build_pgo-2.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue17667> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
