BOOST_TEST_REPORT_LEVEL and BOOST_TEST_LOG_LEVEL crash on Mac OS X with g++ 4.6.1

[Thomas Krennwallner <tkren@…>]

Using the environment setting BOOST_TEST_REPORT_LEVEL=detailed and BOOST_TEST_LOG_LEVEL=all frees an unallocated pointer on mac os x when running simple boost unit tests compiled with g++ 4.6.1; standard g++ 4.2.1 has not this problem:

$ g++ -DBOOST_TEST_DYN_LINK -I/opt/local/include -L/opt/local/lib -lboost_unit_test_framework-mt boost_test.cxx 
$ ./a.out
Running 1 test case...

*** No errors detected
$ BOOST_TEST_REPORT_LEVEL=detailed BOOST_TEST_LOG_LEVEL=all ./a.out
Running 1 test case...
Entering test suite "boost_test"
Entering test case "mytest"
boost_test.cxx:4: info: check true passed
Leaving test case "mytest"; testing time: 40mks
Leaving test suite "boost_test"

Test suite "boost_test" passed with:
  1 assertion out of 1 passed
  1 test case out of 1 passed

  Test case "mytest" passed with:
    1 assertion out of 1 passed

Compiling with g++ 4.6.1 gives

$ g++-mp-4.6 -DBOOST_TEST_DYN_LINK -I/opt/local/include -L/opt/local/lib -lboost_unit_test_framework-mt boost_test.cxx 
$ ./a.out

A backtrace does not give too much information:

BOOST_TEST_REPORT_LEVEL bug on mac os x

[Gennadiy Rozental]

I do not have access to MacOS. Works fine with gcc 4.6.1 under Ubuntu. backtrace points to the system iostreams. I will not be able to move any further without more information, but I doubt frankly this is Boost.Test issue.

Having the same problem with 4.7

[Gennadiy Rozental]

I do not have an access to Macs and it works fine both in regression tests and on Linux with similar setup. I do not see any indication yet this is Boost.Test issue. Once you have patch or more concrete pointer to the error in a code please resubmit the issue
