Hi, Building solib-target.c on host where CORE_ADDR != ULONGEST is broken, because of this: static void library_list_start_segment (struct gdb_xml_parser *parser, const struct gdb_xml_element *element, void *user_data, VEC(gdb_xml_value_s) *attributes) { VEC(lm_info_p) **list = user_data; struct lm_info *last = VEC_last (lm_info_p, *list); ULONGEST *address_p = VEC_index (gdb_xml_value_s, attributes, 0)->value; VEC_safe_push (CORE_ADDR, last->segment_bases, address_p); } Pushing a ULONGEST* into a CORE_ADDR VEC doesn't work. I'm using the attached patch to try to catch invalid data send by a (remote) target, but I guess it isn't correct for all archs. I was building arm-wince-mingw32ce on i686-pc-cygwin.
