3.0-pre crashes on i686 code

[Teemu Torma <tot at trema dot com>]

I have a piece of code that crashes when compiled with -O -march=i686
(version from the cvs today).  This used to work couple of weeks back,
and it compiles if either -O or -march is omitted.

Is a proper bug report needed or is this some temporary problem?
