--- Comment #5 from Andrew Macleod <amacleod at redhat dot com> --- My cross compiler doesn't seem to exhibit this behaviour. It simply compiles this as a quite short program. It looks like it in the DOM pass.. could you try it with: -fdump-tree-all-detail --param=ranger-debug=all stop it very shortly after it runs, if it is in a loop of some sort, one of these output files is going to grow very quickly.. probably one of: t.c*dom2 or t.c*dom3 I might be able to tell from the debug output where the cycle is. Doesnt need to be attached here, you could just email it to me. Or is there some other way to reproduce this? I don't have access to a s390 at the moment. Any chance the compiler is miscompiled? does the same thing happen with a stage 1 compiler?
