>Description:

Some programs reliably crash if security.pax.aslr.global is set to 1. Using 
paxctl
to disable ASLR for these programs as a workaround has no effect.

>How-To-Repeat:

# useradd blah
useradd: Warning: home directory `/home/blah' doesn't exist, and -m was not 
specified
useradd: Can't add user `blah': pw_mkdb failed

$ printf 'all:\n\techo\n' > ~/tmp/Makefile && cd ~/tmp && gmake
echo
gmake: *** [all] Abort trap

The flags set with paxctl on gmake have no effect whatsoever:
$ paxctl /usr/pkg/bin/gmake
PaX flags:
  a: ASLR, explicit disable
  m: mprotect(2) restrictions, explicit disable

Likewise setting security.pax.aslr.global=0 and enabling ASLR with paxctl for 
gmake
does not cause a crash. The flag seems to be completely ignored.

The trace shows that __stat30() and readlink() fail for existing accessible 
files:
