5444	boost::pool<>::ordered_malloc() crash	philippeb8@…	Chris Newbold	"Greetings,

I have a segmentation fault detected in Cygwin triggered by a call to boost::pool::ordered_malloc().  The test application can be found in the Shifted Pointer library of the Sandbox:
$ svn co http://svn.boost.org/svn/boost/sandbox/shifted_ptr
$ cd shifted_ptr/libs/smart_ptr/example
$ make shifted_ptr_test3

Gives the following backtrace:
