Starting nbench after compiling it with -ftree-loop-linear leads to an endless
loop in the 'neural net' benchmark. This is reproducible with gcc-4.0.0 to
gcc-4.0.2.
I haven't looked at the preprocessed source for now, sorry.

It is the same as 20256, so please remove this duplicate, i checked the sources
of nbench.
Sorry for sending too few information.

Subject: Re: [4.0] endless loop in nbench

btw, i will get around to fixing these after i merge all the stage1
projects i'm working on.

------- Comment #4 from pinskia at gcc dot gnu dot org 2006-03-08 15:17 -------
Is there a testcase other than just compile and run nbench with
-ftree-loop-linear?

Yes, see PR20256: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20256
This is just a duplicate bugreport.
