[Boost-users] problems using overloaded output operator with program_optoins::optoins_description in debug mode vc++ 7.1

Hi

I'm trying to use the program_options header to satisfy my command line 
needs, and I have have run into the following quirk with boost version 
1.32 and microsoft visual c++ 7.1 when trying to use 'cout<<' to output 
the program_options::options_description.
Appartently there is a limit to the length of the program option name.

When not specifying short optoins names, the option name seems to be 
limited to 12 characters.  greater than this and I get a debug assertion 
failure in dbgheap.c line 1132 expression: 
_CrtIsValidHeapPointer(pUserData) .

When specifying a short option name, the limit for the full name seems 
to be 6 characters.  More than this results in a debug assertion falure 
in debug mode (msvc++ 7.1, file dbgdel.cpp, line 52) 
_BLOCK_TYPE_IS_VALID(pHead->nBlockUse).
Is there something I can do to to fix this or work around the problem 
(besides restricting the length of my option names)?  Is this a compiler 
specific problem?  Something wrong with my settings?

many thanks,

Glen Stark
