parse_fdinfo: Don't advance pointer twice [BZ #31798]
pidfd_getpid.c has /* Ignore invalid large values. */ if (INT_MULTIPLY_WRAPV (10, n, &n) || INT_ADD_WRAPV (n, *l++ - '0', &n)) return -1; For GCC older than GCC 7, INT_ADD_WRAPV(a, b, r) is defined as _GL_INT_OP_WRAPV (a, b, r, +, _GL_INT_ADD_RANGE_OVERFLOW) and *l++ - '0' is evaluated twice. Fix BZ #31798 by moving "l++" out of the if statement. Tested with GCC 6.4 and GCC 14.1. Signed-off-by: H.J. Lu <hjl.tools@gmail.com> Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org> (cherry picked from commit f981bf6b9db87e0732b46bfe92fdad4d363225e8)
