Yes, APAR IY25528 is applied already.

This build bombs out with a core dump.  Where in the bootstrap the core dump happens depends on the config line (see "how-to-repeat"), but happens within the same bfd function.

I have not been able to fix this by using an older version of binutils either.  Any ideas?


With the first config line (--without-gnu-as --without-gnu-ld):
