I am trying to run Lazarus (build 9246) on x86_64-redhat-linux with FPC

It seems as if the exception occurs in the following piece of code:
CurScale:=double(Child.MinimumSize[Orientation])
/Child.PreferredSize[Orientation];
A hack around this issue is to insert an exit command just before line
616 in wincontrol.inc, but this obviously stuffs up resizing and
probably has other side effects too.
I have analyzed this problem and it is a bug in code generator. A
simple app has been created for the bug report:

That seems to be the same as these bugs
