Maybe this a generic sjlj exception handling problem? I'm not too clear on 
which compiler releases have used this mechanism, but the mingw compiler I have 
certainly does (note the --enable-sjlj-exceptions configure option below). 
Maybe the Linux versions mentioned by Wolfgang Bangerth used different EH 
mechanism between 3.2 and 3.3/mainline?
