------- Comment #3 from gcc at jme dot de 2008-10-07 23:29 -------
Hi Joseph,
because the the problem occurs only with the compiler switch -O.
And the problem occurs not if I place a "printf("xx")" between
the two statements "if" and "for". Therefore, I thought it was a
more target independend optimization problem.
But now I'd checked this behaviour with i386 Linux
(after installing g++ with "apt-get install g++")
-> "gcc-Version 4.0.3 (Ubuntu 4.0.3-1ubuntu5)"
and it works correct there.
I'll post the bug report to the AVR32 Linux site.
Sorry about wasting your time. This was my 1st bug post.
Next time I'll compare the behaviour on my Linux PC before posting.
Thanx,
Joe.(In reply to comment #1)
