Follow-up Comment #3, bug #42717 (project gnustep):
When built with -O1, -calcSizesAllowingNegative: doesn't crash when called
from -setBorderType: (aType there is 3 as expected) but from
-setTitlePosition:
Breakpoint 1, -[NSBox setTitlePosition:] (self=0x921f6b0,
_cmd=0xb7edb618 <_OBJC_SELECTOR_TABLE+600>, aPosition=NSAtTop)
at NSBox.m:192
192 {
(gdb) n
193 if (_title_position != aPosition)
(gdb)
195 _title_position = aPosition;
(gdb)
196 [_content_view setFrame: [self calcSizesAllowingNegative: NO]];
(gdb)
