They appear to be erratic in failing; while trying to track down an originating
revision I was seeing some older revisions work and then later fail.
When they fail they all fail the same way:
spawn -ignore SIGHUP /home/seurer/gcc/build/gcc-trunk/gcc/xgcc
-B/home/seurer/gcc/build/gcc-trunk/gcc/
/home/seurer/gcc/gcc-trunk/gcc/testsuite/gcc.dg/graphite/interchange-3.c
-fno-diagnostics-show-caret -fdiagnostics-color=never -O2 -ffast-math
-floop-nest-optimize -fdump-tree-graphite-all -lm -o ./interchange-3.exe
PASS: gcc.dg/graphite/interchange-3.c (test for excess errors)
. . .
PASS: gcc.dg/graphite/interchange-3.c execution test
