New issue 17888 by [email protected]: Memory leak in IPC::Channel::Channel()
http://code.google.com/p/chromium/issues/detail?id=17888

This looks like it's in the neighborhood of bug 17385,
but the stack looks different enough that I hesitate to call it a dup.

The mac valgrind bot complained several times today, e.g. in
http://build.chromium.org/buildbot/waterfall/builders/Chromium%20Mac%20(valgrind)/builds/364/steps/valgrind%20test:%20unit/logs/stdio
as follows:

6,691 (5,256 direct, 1,435 indirect) bytes in 1 blocks are definitely lost
in loss record 10,901 of 10,965
   operator new(unsigned long)
(tools/valgrind/valgrind-20090715/coregrind/m_replacemalloc/vg_replace_malloc.c:219)

std::allocator<char> > const&, IPC::Channel::Mode, IPC::Channel::Listener*)

   IPC::Channel::Channel(std::basic_string<char, std::char_traits<char>,
std::allocator<char> > const&, IPC::Channel::Mode, IPC::Channel::Listener*)
(src/xcodebuild/Release/unit_tests)

std::char_traits<char>, std::allocator<char> > const&, IPC::Channel::Mode
const&) (src/xcodebuild/Release/unit_tests)
