This is why POSIX allows implementations to place a limit on the number of repetitions supported in {n,m} (IIRC only up to 256 need to be supported) and why glibc should make use of this allowance. -- You are receiving this mail because: You are on the CC list for the bug. ^ permalink raw reply [flat|nested] 3+ messages in thread
