Re: [Boost-users] [test] detect_memory_leak option in msvc 8
I am trying to get the --detect_memory_leak=1 option to detect a memory leak in my code.
Hi! In MSVC 7.0 the memory leak detection is somewhat primitive (I don't know about MSVC 8). I'm using Boost.Test together with mpatrol and it works great! Here is the output of a test run: <mpatrol_output> top 4 unfreed memory entries in leak table: bytes count location -------- ------ -------- 400 1 d:\[snip]\unittests\test_config.cpp line 10 84 1 d:\[snip]\tcpstream\src\myenv.cc line 145 24 1 c:\src\boost_1_33_1\libs\thread\src\mutex.inl line 55 8 1 c:\src\boost_1_33_1\libs\thread\src\tss_hooks.cpp line 29 516 4 total </mpatrol_output> NB. The first memory leak is intentional, the second is a resource leak from cppadvio. It also detects the already discussed resource leaks in Boost.Treads :) I needed some try-and-error to find the correct versions of mpatrol, Boost.Test and the windows runtime library, but now that it works, it is incredibly useful. (/MDd, mpatrolmt.dll, libboost_unit_test_framework-vc7-mt-gd.lib) Just for comparison, here is the output of the MSVC 7.0 memory leak detection of the same code: <msvc_output> Detected memory leaks!

Thanks for the info. I got it to work by linking against the debug version of the UTF library. Chris On 3/26/07, KLINIK Markus SDI2-G (AREVA NP GmbH) <Markus.Klinik@areva.com> wrote:
