+ max = (1 << (fixP->fx_size * 8)) - 1;
In C, 1 is of type int. When fixP->fx_size is 4, this causes undefined
behaviour if int is 32 bit (on the host).
Also, I fear your replacing of apply_full_field_fix with md_number_to_chars
might
break something else - e.g. a constant with a label or symbol value used for a
pc-relative load.
Have you considered changing apply_full_field_fix instead to check for
SWITCH_TABLE (fixP) ?
i.e.:
if ((fixP->fx_addsy != NULL || fixP->fx_pcrel)
&& !SWITCH_TABLE (fixP))
