Subject: [Bug rtl-optimization/30931] Simple test case loops infinitely with -O1 -fstrength-reduce.

------- Comment #6 from bergner at gcc dot gnu dot org 2007-02-23 14:06 -------
Here's the output you asked for using the latest 4.1 sources I built yesterday.
This also fails for me using the system compilers on Ubuntu Edgy and SLES10.
I'll try and track down a x86 RHEL5 system to test there too.
Please note it's not the compiler that is looping forever, but the built binary
when executed.
