In gcc, -static-libgcc disables exception handling. I don't know if  it is enabled by -static.

Thank you for your reply Laurent. While making a simple example to
send to you, I have solved the problem. I removed the "-static"
compiler option and now it works. But I am not sure why wouldn't it
work with -static. I have read somewhere that CGAL won't link against
static blas libraries but uses dll instead, so I guess that this could
be related. Anyway, if you think that this should be looked into, the
example is in the attachment.
