Upgrading from a hardened glibc-2.3.6-r5 to a hardened glibc-2.5-r2 (and after a reboot), a bug in dosemu was triggered. A hardened dosemu-1.3.2 failed with: *** stack smashing detected ***: dosemu.bin - terminated dosemu.bin: stack smashing attack in function setup_default_keytable - terminated Report to http://bugs.gentoo.org/ Killed Upgrading to dosemu-1.4.0, it still failed, now with: *** stack smashing detected ***: dosemu.bin - terminated dosemu.bin: stack smashing attack in function X11_DetectLayout - terminated Report to http://bugs.gentoo.org/ Killed Compiling dosemu-1.4.0 with the vanilla compiler gets it going again.

hardened-team, please comment on that
I get the same error.
Do you get it when starting it or when using it?
looks like a crash on keyboard layout setup so that would be on configuration before the dos is started
Still the same with 1.4.1_pre20091009?
Closing as WORKSFORME. Please repoen if it's still the case on app-emulation/dosemu-1.4.1_pre20130107-r2 and add some steps to reproduce.
