Hi,
I am seeing a double free when using boost-test on:
- FreeBSD 7.2-STABLE, amd64 (gcc 4.2.1) with boost 1.39 - Mac OSX 10.6.1, x86_64 (XCode 3.2, gcc 4.2) with boost 1.40
Hi! I tried your example on 32bit Linux with boost 1.38 and 1.40 and gcc 4.4.1, 4.3.2 and 4.1.2. Everything works fine. Results are: krivenok@develop2 17:22:16 /tmp/test_bug $ cat test.cpp #define BOOST_TEST_MAIN #include <boost/test/included/unit_test.hpp> #include <stdlib.h> const char* _malloc_options = "J"; BOOST_AUTO_TEST_CASE(broken) { BOOST_CHECK(true); } krivenok@develop2 17:22:31 /tmp/test_bug $ g++-4.4.1 -Wall -I /usr/local/dev/boost-1.40.0/include/ test.cpp -o test krivenok@develop2 17:22:45 /tmp/test_bug $ ./test Running 1 test case... *** No errors detected krivenok@develop2 17:22:48 /tmp/test_bug $ g++-4.3.2 -Wall -I /usr/local/dev/boost-1.40.0/include/ test.cpp -o test krivenok@develop2 17:23:02 /tmp/test_bug $ ./test Running 1 test case... *** No errors detected krivenok@develop2 17:23:04 /tmp/test_bug $ g++-4.1.2 -Wall -I /usr/local/dev/boost-1.40.0/include/ test.cpp -o test krivenok@develop2 17:23:16 /tmp/test_bug $ ./test Running 1 test case... *** No errors detected krivenok@develop2 17:23:18 /tmp/test_bug $ g++-4.4.1 -Wall -I /usr/local/dev/boost-1.38.0/include/ test.cpp -o test /usr/local/dev/boost-1.38.0/include/boost/test/floating_point_comparison.hpp:224: warning: 'boost::test_tools::<unnamed>::check_is_close' defined but not used /usr/local/dev/boost-1.38.0/include/boost/test/floating_point_comparison.hpp:246: warning: 'boost::test_tools::<unnamed>::check_is_small' defined but not used krivenok@develop2 17:23:41 /tmp/test_bug $ ./test Running 1 test case... *** No errors detected krivenok@develop2 17:23:43 /tmp/test_bug $ g++-4.3.2 -Wall -I /usr/local/dev/boost-1.38.0/include/ test.cpp -o test /usr/local/dev/boost-1.38.0/include/boost/test/floating_point_comparison.hpp:224: warning: 'boost::test_tools::<unnamed>::check_is_close' defined but not used /usr/local/dev/boost-1.38.0/include/boost/test/floating_point_comparison.hpp:246: warning: 'boost::test_tools::<unnamed>::check_is_small' defined but not used krivenok@develop2 17:23:54 /tmp/test_bug $ ./test Running 1 test case... *** No errors detected krivenok@develop2 17:23:56 /tmp/test_bug $ g++-4.1.2 -Wall -I /usr/local/dev/boost-1.38.0/include/ test.cpp -o test krivenok@develop2 17:24:10 /tmp/test_bug $ ./test Running 1 test case... *** No errors detected krivenok@develop2 17:24:15 /tmp/test_bug $ I will try it on amd64 later.
I don't see the problem on Windows XP with Visual C++ 2005 Express.
A simple test case is below, just run. The _malloc_options is to make the system malloc() fill memory with 0xa5 on allocation and 0x5a on deallocation.
#define BOOST_TEST_MAIN #include <boost/test/included/unit_test.hpp> #include <stdlib.h>
const char* _malloc_options = "J";
BOOST_AUTO_TEST_CASE(broken) { BOOST_CHECK(true); }
Output:
Running 1 test case...
*** No errors detected zsh: bus error (core dumped) ./a.out

Any ideas?
