This is a potential security problem. This should never ever be necessary. Stack memory is not executable on most OSes these days and this will not change. Executable stack memory is one of the biggest security problems. An execstack error might in fact be most likely raised by malicious code. Applications are sometimes coded incorrectly and request this permission. The <a href="http://people.redhat.com/drepper/selinux-mem.html">SELinux Memory Protection Tests</a> web page explains how to remove this requirement. If $SOURCE does not work and you need it to work, you can configure SELinux temporarily to allow this access until the application is fixed. Please file a bug report. a6 Sometimes a library is accidentally marked with the execstack flag, if you find a library with this flag you can clear it with the execstack -c LIBRARY_PATH. Then retry your application. If the app continues to not work, you can turn the flag back on with execstack -s LIBRARY_PATH. � zfIf you do not think $SOURCE_PATH should need to map stack memory that is both writable and executable.zByou need to report a bug.
