Here's a one line patch for rc-1.5b2 which fixes a thinko in the autoconf support. If you've had problems with rc dumping core, or refusing to execute files which your group permissions allow you to, this patch should fix them. These problems have been experienced under SunOS 4. This patch will be incorporated into the next official beta release of rc, rc-1.5b3, which I hope to make as soon as I've fixed a race condition in the wait() code. (Experienced under Linux 2.0.30 on a dual processor machine; I suspect it wouldn't occur on a single processor.) Please continue to let me know of any problems or successes you've had with rc-1.5b2. Thanks, Tim. --- which.c 1997/07/01 20:02:57 1.2 +++ which.c 1997/09/15 10:27:18 @@ -88,7 +88,7 @@ gid = getegid(); #if HAVE_GETGROUPS ngroups = getgroups(0, (gid_t *)0); - gidset = malloc(ngroups * sizeof(gid_t)); + gidset = malloc(ngroups * sizeof(GETGROUPS_T)); if (!gidset) uerror("malloc"); else
