MonoDevelop 22.214.171.124 sets this flag on the unix executable in the app bundle.
You can see this by navigating within your package.app/Contents/MacOS
directory in terminal and doing otool -h <executableName> on the one file in
this directory. You will see that in the flags field to the right, the no
heap execute bit is set:
This is good from a security standpoint. Unfortunately, Silverlight has
issues with this, so this keeps me from using a webView to write a browser
wrapper that navigates to silverlight content. (Silverlight's issue with no
heap execute has been encountered by others - firefox solved it by forcing
silverlight to run out-of-process even in 32 bit firefox - see
The best I can come up with in MonoDevelop is to try to turn the no heap
execute flag off manually using a hex editor. Is there any other way? Could
we consider adding it as an option to pass down somewhere in the MonoDevelop
