hi all,
my application uses boost::property_map to, well, store properties ... it
basically works fine, however, when compiling the application with
_GLIBCXX_DEBUG, the xml grammar parser complains:
/usr/include/c++/4.2/debug/safe_iterator.h:131:error: attempt to copy-
construct an iterator from a singular iterator.
Objects involved in the operation:
iterator "this" @ 0x0xbfe46690 {
type =
N11__gnu_debug14_Safe_iteratorIN9__gnu_cxx17__normal_iteratorIPKcNSt6__norm6vectorIcSaIcEEEEENSt7__debug6vectorIcS7_EEEE
(constant iterator);
state = singular;
}
iterator "other" @ 0x0xbfe467e0 {
type =
N11__gnu_debug14_Safe_iteratorIN9__gnu_cxx17__normal_iteratorIPKcNSt6__norm6vectorIcSaIcEEEEENSt7__debug6vectorIcS7_EEEE
(constant iterator);
state = singular;
}
the backtrace of the problem is:

<snip>
i am not sure, whether this is a property_map or a spirit problem, nor if
it is a problem at all ...
the problem occurred on boost-1.34.1, using the property_map archive from
the vault. although the code works fine, it keeps me from debugging my
application with _GLIBCXX_DEBUG, so it would be great if this could be
fixed ...
btw, boost::property_map from svn doesn't compile against boost-1.34.1 (i
didn't try compiling it against boost-svn, though):
