Hi Dan,

I have not seen that on macOS before,  but previously ran into other issues.  
This may help to chase it down:

build with use 
        CFLAGS=-g LDFLAGS=-g ./configure --disable-shared --prefix=/opt/local

in meta/gdb-uninstalled-guile, change:
    gdb --args ${top_builddir}/libguile/guile "$@"
to
    lldb -- ${top_builddir}/libguile/guile "$@"

and, IIRC, run meta/gdb-installed-guile
