Ronald Oussoren added the comment: There could be an off by one error in the decoding of PYTHONEXECUTABLE, mbstowcs will only add a NUL character when there is room for one and when the environment variable is all ASCII the buffer isn't large enough which means the argument to Py_SetProgramName is not NUL-terminated unless there happens to be a NUL byte just beyond the allocated buffer.
The attached patch ensures that there is room for a NUL character. I don't know if this actually fixes the crash as I've been unable to reproduce the issue (with various values of PYTHONEXECUBLE and with/without malloc checking environment variables (see malloc(3)). ---------- Added file: http://bugs.python.org/file26958/issue15761.txt _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue15761> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
