Not really, there are about 300 lines of new code (mostly in a new routine).
It might be that only the change in can_reassociate_p is needed to fix this
bug.
That would be a pretty eas

Based on my posted test results for hppa2.0-hp-hpux11.11, this PR was
fixed on the trunk between r163182 and r163254.
Need to find the change.

Any idea what could be done from the gfortran side? Without being able to
reproduce it, it is a bit difficult to debug :-(

When compiled with -O2 -Wuninitialized, the reduced test of comment #3 gives

I think the problem is related to the fact that IRA is trying to figure out if
the store of lx1 can be eliminated and lx1 may be uninitialized. The only
place lx1 is set is in an if statement in a loop. If we don't exec

Since the failure requires -O1 as well as -fbounds-check I tried turning off
various -O1 optimizations. I could turn off everything (and still get the bug)
except if I use -fno-tree-dominator-opts or -fno-guess-branch-pr

differences in the trees, just differences in the names of genera

An ice is an ice. However, this is particularly nasty to me since it is trying
to use reals for index variables.
Have you tried to get this down to a single loop and get the ice?
