Title: sf::Text destructor crashes app
Post by: Groogy on January 19, 2009, 10:13:12 pm

It's probably me that has done something wrong. But every time I try to run my application with sf::String it crashes when it shuts down(working perfectly until then). When I uncomment the line where I create the object the error disappears.

Can't see what's wrong.

Since it crashes for me at the end too sometimes i tested it with sf::String and SFML.Graphics.String2D from SFML.net and both times the program crashes at then end once i have a variable of that type in it.

I don't know much of the internal functions of the library.

But I'm working at Windows at the moment, but it feels like I would get a SEGMENTATION FAULT if I would have done this in Linux. So my guess is that somewhere we tries to dealloc NULL or something.

It happens when the default font is destroyed (so it won't happen if it doesn't get instanciated).

I've already worked hard on this issue, and I have no clue so far :(

Your sure it's the font? Since It happens when the String is removed? I'll have a look at the source code and see If I can find anything.

Does this happen for everyone or is it isolated?

Hmm you don't have a destructor for either classes. Couldn't be that the default destructor is messing something up? Though I can't think of a reason why it would.

I'll put some cout here and there and see if I can narrow down the error.

Wierd thing, you said the default font did it? I told my sf::String object to use another font with: "text.SetFont(font);" but I still get the same thing.
Do I have to use the constructor to avoid the error?

Yes, because the constructor instanciates the default font in case you don't specify another one.
