Hello,

I have found memory leak in FreeType code. What's wrong this time? Ultimate++ never closes FreeType library on POSIX.

I have written simply function (FontFc.cpp - line 31):
bool sDoneFt()
{
	if(sFTlib)
		return FT_Done_FreeType(sFTlib) == 0;
}


This function should release major part of memory that was allocated by FreeType. I have tested it using following EXITBLOCK:
EXITBLOCK 
{
    sDoneFt();
}


But, there is one problem. I don't know where we need to invoke this function in upp library. I have looked at Font.cpp, but I can't find good place there.

Sincerely,
Klugier

What is the problem with putting EXITBLOCK there? (Applied the fix there).
