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. -- Alper Aydemir On Thu, Apr 5, 2012 at 3:25 AM, Martin Searancke wrote:

I have just upgraded my Mac to Lion and code that worked fine under snow leopard is giving me a run-time exception when constructing a directory_iterator.

The error I am getting is "malloc: pointer being freed was not allocated"

The line in question that raises this error is:        for ( directory_iterator itr( my_path ); itr != end_itr; ++itr ) taken directly from the example and working fine under windows.

This is version 1.49 installed with MacPorts.

Is this a known problem? I found some vague references to a similar problem in an earlier version of boost but no solution.

I have confirmed that I only have 1 copy of the headers and libs on the system and in the correct path. The date stamp on the files matches the last time I did a macports update so this should be the matching library for the header. Please note that I am a real novice to Mac development and have only just started porting code from windows for less than a month.
