Great. Before I forget, I have created a patch for clocale which has been committed in svn 17919. Before the patch exceptions where created in functions like DateToStr. > Second, on SPARC Linux (Debian "Lenny") running on a Sun > Ultra-1 with a > minimal project (button on form -> close) I get this during > "Build All": > > Compiling project1.lpr > Compiling unit1.pas > unit1.pas(16,25) Hint: Parameter "Sender" not used > Assembling unit1 > Assembling project1 > Compiling resource /home/markMLl/lib/sparc-linux/project1.or > > Program received signal SIGBUS, Bus error.

So, yes, that is asking for non-aligned access? There are several similar constructs in SynRegExpr. That is going to be a non-trivial fix, I'm afraid. > gtk2callback.inc:2406 #16 0xf787cb40 in ??

The lazarus routine is triggered by a timer and, if I understand this correctly, you are in the routine that is scanning the messages window and puts icons in front of the messages. Here it is looking for "Unit x not used in y" messages. You can check "Hide Messages Icons" in Tools/IDE Options/Window to get around this one, for the time being. > > Third, on ARM Linux (Debian "Lenny") running natively on an > NSLU2 "Slug" > I appear to get a failure building a program.
