 Hello!
 
 I'm sorry for flooding three lists at a time, but I have some
 information concerning ports/72014 and it looks like I've reached that
 point where I can't do further investigation. So I hope someone who has
 more knowledge, experience and free time will handle this further.
 
 I made some investigation of this bug and it looks like it is cased by
 gtk built with CPUTYPE=p4. Eclipse works fine after changing CPUTYPE to
 i686 and rebuilding/reinstalling gtk. This is true for my P4 box and
 this was also confirmed by two other testers who faced similar problem.
 Eclipse also works fine with CPUTYPE=athlon-xp (my amd based box at
 work).
 
 So I think this is gcc bug which leads to wrong code in gtk, and I
 suppose it can lead to other bugs with gtk. I've seen SIGBUSes in 
 _gtk_tree_view_queue_draw_node and gtk_tree_view_get_column with -O0/-O
 and -O2 respectively. I'm not sure what should be done further. I
 thought of following:
 
 - building debug version of gtk, looking what arguments are passed to
 those functions and trying to create a test case to submit bug report to
 gcc team;
 
 - trying to build gtk with more recent gcc;
 
 - downgrade CPUTYPE from p4 to i686 in x11-toolkits/gtk20 until this
 problem is solved.
 
 Unfortunately I don't have any gtk development experience and I don't
 know what should be the best solution for this problem. I'm posting
 results of my investigation in hope that someone will handle this bug
 further.
 
 p.s. And I think this is not freebsd-java bug, so responsible in PR
 database should be changed to someone else.
 
 p.p.s. I'm not on the lists, so keep me on To: or Cc: lines if you want
 to reply me.
 
 p.p.p.s This mail is probably in a mess a little bit. Sorry, I couldn't
 put it into right words.
