Liviu Nicoara commented on STDCXX-1071: --------------------------------------- The file punct-mt.cpp is a multi-threaded program that tests either the numpunct or the moneypunct facet accessor interface. If TEST_MONEYPUNCT is defined, the test tests moneypunct. The test fails with 4.2.x and presumably with all others. The moneypunct version does not fail in my local runs. I have used SUNPro 5.12 on Linux, but I noticed failures with gcc 4.7.1 as well. The test case is pointing at the numpunct facet caching code. > numpunct facet cache initialization is not thread -safe > ------------------------------------------------------- > > Key: STDCXX-1071 > URL: https://issues.apache.org/jira/browse/STDCXX-1071 > Project: C++ Standard Library > Issue Type: Bug > Components: 22. Localization, Thread Safety > Affects Versions: 4.2.1, 4.2.x, 4.3.x, 5.0.0 > Environment: $ uname -a; CC -V > Linux behemoth 2.6.37.6 #3 SMP Sat Apr 9 22:49:32 CDT 2011 x86_64 AMD > Opteron(tm) Processor 6134 AuthenticAMD GNU/Linux > CC: Sun C++ 5.12 Linux_i386 2011/11/16 > Reporter: Liviu Nicoara > Priority: Critical > Labels: DCII, localization, numpunct, thread-safety > Fix For: 4.2.1, 4.2.x, 4.3.x, 5.0.0 > > Attachments: library-reduction.cpp, punct-mt.cpp > > Original Estimate: 8h > Remaining Estimate: 8h > > The bug affects the initialization of the cached data in numpunct facet. The > failing test is 22.locale.numpunct.cpp in certain builds: Linux with SUNPro > 5.12, optimized, most likely to fail. It has been reported (see linked > incidents) to fail on SPARC as well. It manifests in variate ways: sometimes > as heap corruption, sometimes as access violations, etc. Test cases and > library reduction programs to follow. -- This message is automatically generated by JIRA.
