Differences between revisions 2 and 6 (spanning 4 versions)

There are still some programs that have executable stack regions.

open bugs in LP
check an ELF binary: "readelf -l $BIN | grep GNU_STACK" shows with "E" flag.

Main/Restricted Packages

Originally generated from the ELF files with executable stacks in Karmic main.

Uses Nested Functions which compiler generates as trampolines on the stack.
