How to debug drmemory's invalid heap argument errors

I've just ran into a drmemory error with my application with the following output:

Error #1: INVALID HEAP ARGUMENT to free
# 0 replace_operator_delete                            [d:\drmemory_package\common\alloc_replace.c:2496]
# 1 std::vector<>::~vector()                           [C:/Qt/Tools/mingw482_32/i686-w64-mingw32/include/c++/ext/new_allocator.h:110]
# 2 msvcrt.dll!exit      
# 3 _fu0___set_invalid_parameter_handler               [C:/Qt/Tools/mingw482_32/i686-w64-mingw32/include/c++/bits/stl_tree.h:1809]
# 4 KERNEL32.dll!BaseThreadInitThunk                  +0x11     (0x7651338a <KERNEL32.dll+0x1338a>)

I've absolutely no idea where to start looking for my bug. Does anybody have some idea? (The application I've run is quite complex, so I can't post thousands of lines here.)
