--- Comment #2 from Sergei Trofimovich <slyfox at inbox dot ru> --- Commenting out 'GETA $2,LC:0' makes assembler get past the error. 'LC:0' is defined in '.rodata'. If I change '.rodata' manually to '.text' assembler can assemble ELF file from modified source. I guess 'fixup not contained within frag' is an equivalent of 'relocation points outside current ELF section'.
