std::auto_ptr used wrong

std::auto_ptr can't be used with arrays, example:

"std::auto_ptr<char> bad( new char[100] );"

std::auto_ptr use "delete ptr" and _not_ "delete [] ptr"

Location found:
RELEASE_0_47_PRE4_BRANCH/src/libnrtype/FontInstance.cpp
Line: 461

and since it's used there you should search the whole project for more of the same bug

side note: boost have a scoped array class that can be used (or you can make your own version, usually not recommended)
