How did you change the font to a negative number? I opened the Fonts preference and it only allows a drop down box selection.

No. I set negative font size of BFont object. See attached program.

I compiled and tested this on a GCC4 compiled alpha3 RC Haiku at hrev41768 and I did not see the lockup. Could you test again X512, since it has been a year?

Works fine with GCC2 as well, on hrev41884.

The Be Developer's Guide c1997 says on page 432 that BFont SetSize() valid sizes range from less than 1.0 point through 10000 points. So perhaps we should add a range check to SetSize() to limit the valid inputs?

Replying to leavengood:

I can't reproduce bug in hrev43243. But it can be unhandled behavior and arguments check needed in app_server.
