problems with gcc4.7 and --std=gnu++11

Did you also recompile Boost with --std=gnu++11? What's the difference between this flag and -std=c++11?

No, Boost was compiled with their default flags (multithreaded), but with gcc4.7. The differences are not much I think, some extensions that GNU adds that technically break spec. The segfault happens with either c++11 or gnu++11.

Can you test with the latest commit? If your code still crashes, try to find a minimal example and post a backtrace of a debug build.

std=c++11 gave a little more detail in the stacktrace when it segfaulted, the relevant part is:

ompl::base::Planner::~Planner (this=0xe0e300, __in_chrg=) at /home/dkg1/omplapp/ompl/src/ompl/base/Planner.h:258
boost::checked_deleteompl::geometric::KPIECE1 (x=0xe0e300) at /home/dkg1/include/boost/checked_delete.hpp:34

(Verified with latest commit, everything was in Debug except Boost. I'll start looking for simple examples, or construct one.)

Aha, the segfault was in my code, I had two boost pointers to the planner separately constructed from the raw pointer. That was not an OMPL issue.
