Disambiguating symbols by module

[Alexander Miloslavskiy <alexandr.miloslavskiy@gmail.com>]

Hello,

I spend much time debugging Java with GDB.

In order to obtain current Java callstack, I do this:
(gdb) call (void)ps()

The problem is, the function's name is too short and gdb confuses it 
with a variable in a different library:

(gdb) info var ^ps$
File ../../cipher/blowfish.c:
256:	static const u32 ps[18];

(gdb) info function ^ps$
Non-debugging symbols:
0x00007ffff6d7a3b0  ps

Here, the symbol I want is a non-debugging symbol. This also means that 
I can't disambiguate it by the source file name.

Is there a syntax to disambiguate the symbol?
