I can confirm that this also happens on Mac OS 10.6.8

minimal code sample:

const char * path_str = "/data/jpegs_highmotion";
path pdir =path_str;

for(directory_iterator dit = directory_iterator(pdir); dit!=end;
++dit, ++frameNo ){
...

}

It crashes on the for loop line with:

#3  0x00007fff854c0124 in std::string::assign ()
#4  0x000000010086d8cb in
boost::filesystem3::detail::directory_iterator_construct ()
#5  0x00000001000038e0 in directory_iterator (this=0x7fff5fbff3f0,
p=@0x7fff5fbff410) at filesystem/v3/operations.hpp:606

demo(7898) malloc: *** error for object 0x10094b540: pointer being
freed was not allocated

Would be good to fix this as it's a quite frequently used part of the code.
