Found the problem.
The NetBSD build procedure for libraries has a rather peculiar compile
step, which includes running the file through ld with a -x switch.
That will do it... It's not supposed to do that if a -g is present in
the compile options; that may be an error in the top level build
process at our end.
That does leave this puzzle:
Given such a shared library (no local symbols in the symtab),
"disassemble somestaticfunc" works fine if I open the shared lib
itself with gdb. But if the shared lib is referenced via the shared
lib symbol load machinery, for example because a corefile pointed to
it, then the same disassemble command doesn't work.
It looks like the code in blockframe.c that pulls in the psymtab to
double-check the function (if an end address was requested) doesn't
work in that second case. Does that make sense?
