Information like "main, line 37 of lazarus.pp" results from the lineinfo unit (= -gl option).
The reason why you get stupid lineinfo like "UNIONRECT,  line 74 of graphics.pplcllinux.pp" is, that the access violation was raised in gtk code and there is no line information available for this code. This can mean that the gtk has a bug. But I think, the bug is located somewhere in the gtk-interfaces of lazarus, because I found and fixed a couple of them in the last few weeks. This kind of bugs are very difficult to track down.
Is the bug reproducable or does it only sometimes occur? Does it happen always at the same point?
