It was not reproducible for me but the problem is Vladimir's i386 crti.S has
DW_AT_ranges which overlap the main code (due to its .fini part).  The main
code full-symbols get ignored now due to it.

Going to post a fix (try to load symtab for each matching psymtab?) and an
updated testcase.


Thanks,
