[lazarus] Lazarus hanging/crashing

[Shane Miller]

I agree it's in the compiler. I disabled the OPPAINT assignment and the ONDESTROY assignment in lazarus (main.pp) and changed the TControl(data).windowproc to dispatchs and now Lazarus runs!
There was something changed in the compiler that has stop functioning.  Can someone on the compiler (FPC) end comment so we know you are looking into this please......

allright, it took some time (I used the wrong symlink :-) but here are some
results of different compilers. It looks like there is something changed in
the latest versions (only the 11/11 version is ok). As a final test I'll do
a make_really_really_really_really_clean and rebuild all to see if
something changes.
