Hide Forgot
I have RH 6.2 installed. Using the upgrade agent, I upgraded my mailx-8.1.1-10.i386.rpm to mailx-8.1.1-16.i386.rpm. After the upgrade, whenever I run mail, open a message to view, and then exit mail, I get a segmentation fault and core dump. See the support incident #154690. I have uninstalled mailx-8.1.1-16.i386.rpm, and restored mailx-8.1.1-10.i386.rpm. Mail now works properly. I have core files I can email to you if necessary.
I have observed the same problem. It does not always core dump, but can be reliably made to do so by almost any activity in mail and then the 'q' command.
I got some free time and decided to look at this myself. The bug was introduced with the patch mailx-8.1.1-environ.patch. After applying this patch, the file fio.c contains case '&': if (name[1] == 0 && (name = value("MBOX")) == NOSTR) if (name[1] == 0 && (name = getenv("MBOX")) == NOSTR) name = "~/mbox"; /* fall through */ The first "if" results in name == NULL and the second if evaluates name[1]. Hence the core dump. It should look like case '&': if (name[1] == 0 && (name = value("MBOX")) == NOSTR) if ( (name = getenv("MBOX")) == NOSTR) name = "~/mbox"; /* fall through */ A diff for the patch is appended. Though patching patches may not be a good idea.

This is the same problem as bug #15728, fixed in Raw Hide but not in the Red Hat 6.2 errata.
Well, many of us are not permitted to see bug #15728. I should have mentioned that a workaround is to add the line set MBOX=~/mbox to your .mailrc file.
I have the same problem upgrading from mailx-8.1.1-10.i386.rpm and mailx-8.1.1-11.i386.rpm. I have many users do not want to remember yet another admin step. Can't mailx be officially re-released with the fix some time soon?

If this is fixed then why is the lates version of mailx in the redhat updates directory still mailx-8.1.1-16.i386.rpm and mailx-8.1.1-16.src.rpm ?
Still no mailx-8.1.1-20 on the updates site in the SRPM or the i386 directories. Why has this been resolved?
I can find mailx-8.1.1-21.*.rpm from Polished linux on rpmfind network. Up2date wants to install mailx-8.1.1-16 when using mailx-8.1.1-10 from RH 6.2 unless the Polished version is installed. Once mailx-8.1.1-16 is installed, it just crashes.
