Re: [ros-dev] [ros-diffs] [fireball] 34232: Yuri Sidorov <[e-mail]> - Prevent boolean flags from being optimized away by compiler (due to PSEH usage) by making them volatile. See issue #3408 for more details.

[Timo Kreuzer]

What about wrapping the _SEH_TRY part in a local inline function? In my 
tests this successfully prevented the variables from being optimized 
away. At least under normal optimisation settings.

_SEH_TRY
{
   void inline tryblock()
   {
   ...
   }
   tryblock();
}
...
