So... from the log file:

/usr/local/src/trunk/objdir-binutils/ld/ld-new  -o tmpdir/def -T /usr/local/src/trunk/src/ld/testsuite/ld-scripts/defined.t tmpdir/def.o
child killed: segmentation violation

and then debugging with gdb:

Again, from the log file:

and debugging with gdb:

so same problem I guess.
