Would you mine testing GCC6? IIRC exception handling is broken in 6,
which is why it is stuck in test.

I suppose I can put gcc 6.3 in test soon.


Jon,

are you building the compilers on cygwin or cross compiling ?

I was trying to test the patch for
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=47030
as it is blocking PETSC porting,
but I was unable to build 6.3.0-1 from your
source package.
