Who built GCC 6.1 for you?  Is this an IBM build or Bull Freeware?

The version of GCC that you are using was built incorrectly.  There
have been problems in the past with some of the pre-built binaries
containing libraries with recently added symbols not correctly
exported.

There seems to be a problem with exception handling and -static-libgcc
in recent versions of GCC on AIX.  I don't know what you have been
testing and why you were not able to triage this.

Thanks, David
