------- Comment #37 from ghazi at gcc dot gnu dot org 2007-06-30 02:22 -------
Run this in a.17.1.i targetted to sparc-sun-solaris2.10 with
--enable-checking=yes,fold and:
cc1 -fpreprocessed a.17.1.i -quiet -dumpbase a.17.1.c -mcpu=v9 -auxbase-strip
a.17.1.s -version -fopenmp -fno-show-column -o a.17.1.s
That should show the error.
