It's definitely not suitable for everyone.
My suggestion was intended to be provocative ;-)
Eric Sandeen had a nice idea: enable it for rawhide,
say by testing for "Rawhide" in /etc/redhat-release.
I propose (seriously, now) to add this to /etc/profile,
or to some always-sourced file like /etc/profile.d/glibc.sh:
# Enable glibc's malloc perturbing feature in Rawhide.
# http://udrepper.livejournal.com/11429.html
read _f _r _n _code_name < /etc/redhat-release &&
case $_code_name in
*Rawhide*) export MALLOC_PERTURB_=$((RANDOM % 255 + 1)) ;;
esac
Alternatively, if we should handle the case of a missing
/etc/redhat-release, and want to avoid generating a diagnostic about it:
if test -r /etc/redhat-release; then
# Enable glibc's malloc perturbing feature in Rawhide.
# http://udrepper.livejournal.com/11429.html
read _f _r _n _code_name < /etc/redhat-release &&
case $_code_name in
*Rawhide*) export MALLOC_PERTURB_=$((RANDOM % 255 + 1)) ;;
esac
