Hi, I have a failing test spencer1-locale for #514. The error is the same as the one reported here: http://lists.gnu.org/archive/html/bug-grep/2012-08/msg00020.html I verified that the error also occurs when compiling with gcc 4.8.0. Here is the snippet for the failing test: ++ grep -E -e 'a(bc)d' ++ echo 0 + status=0 + test 0 -ne 0 ++ echo $'a\002c' ++ LC_ALL=en_US.UTF-8 ++ grep -E -e 'a[^A-^C]?c' ++ echo 0 + status=0 + test 0 -ne 0 ++ echo $'a\002c' ++ LC_ALL=ru_RU.KOI8-R ++ grep -E -e 'a[^A-^C]?c' ++ echo 1 + status=1 + test 1 -ne 0 + echo Spencer test '#514' failed '(ru_RU.KOI8-R)' Spencer test #514 failed (ru_RU.KOI8-R) + failures=1 ++ echo $'a\002c' ++ LC_ALL=fr_FR.ISO-8859-1 ++ grep -E -e 'a[^A-^C]?c' ++ echo 0 + status=0 + test 0 -ne 0 ++ echo $'a\002c' Please let me know if you need more information or access to the build machine.
