Hi Ian, I configured everything from scratch again and it seems that this is reproducible. I also noticed that while running: CGO_LDFLAGS='"-g" "-O2"' /usr/gnu/libexec/gcc/sparc-sun-solaris2.10/8.2.1/cgo -debug-gcc -objdir $WORK/b001/ -importpath command-line-arguments -gccgo -- -I $WORK/b001/ -g -O2 ./sol10.go we see an error: not-type:1:33: error: '__cgo_undefined__2' undeclared (first use in this function); did you mean '__cgo_f_1_2'? Could that be an issue?
This looks awfully similar to https://github.com/golang/go/issues/18959. I also created a bug: https://github.com/golang/go/issues/27838 with all the details.
