Ack.
Note. I do not think the patch about error reporting is to be blamed. We should
say thank you, it opened up an old bug, which used to be ignored. Also it opened
up that modern gcc creates completely crooked undebuggable code. :-)
In this case the patch conceals actual bug, but I believe it is OK.
If we will continue to fall here we will not get any more useful information.
