           Summary: culry is treated as a range in cases where POSIX says

            Status: NEW
          Severity: normal
          Priority: P2
         Component: regex
        AssignedTo: drepper.fsp@gmail.com
        ReportedBy: kevin.braunsdorf@gmail.com

C program to repeat the bug

In the RE "^[$](S|{SHELL}|k|K)$"  the curly braced are not
range specifiers.  Other versions of regcomp accept this RE
with no errors (egrep, *BSD's implmentation and others), but
the later glibc complains:

regcomp: ^[$](S|{SHELL}|k|K)$: Invalid preceding regular expression

(I include a test program for it.)
