This is kind of normal. It is to do with exception handling, which is
specific to the version of gcc being used. The native gcc is being
used for synth and there are many different versions out there. It is
not possible to make this work for all tools. 

Its not a major problem unless you want to do what the test program is
testing, which is unlikely.
