TrampolineCollection iterates over an array of Trampolines that it has set 'write' permissions for. If this happens in a process whose sandbox forbids dynamic code then these permissions cannot be set. This patch detects that condition and returns an empty TrampolineCollection in that case. We ASSERT if we fail to set permissions for any other reason. Differential Revision: https://phabricator.services.mozilla.com/D28613 --HG-- extra : moz-landing-system : lando
