One difference that Solaris has is that you cannot assign 0 to a structure, so something like
 
NSRect rect = [someNilObject rectValue];
 
where someNIlObject == nil, will cause a crash. I try to keep those out of the code, but they tend to creep back in when I'm not looking.

Subject: Problem with illegal instruction ...

Hi,


I try to compile and test gstep-core on Solaris 2.8 / sparc platform. When I run GSTest application and select 'NSTableView' item from 'Tests' submenu I have got error:


Program received signal SIGILL, Illegal instruction.
