Reproduced it under Linux:
	- stripped debug information fromn one my static object library
	- linked one executable (more that one C++ source file) with
	  this library
	- command 'where' showed wrong locations in main.cc for
	  procedures in stripped library

It doesn't seem to happen with shared libraries though, but they are usualy
built with debug info.

Perhaps I should prepare some nice test example to be sent to GDB
mailing list. 

Anyway I think it could also be some problem in linker at time of merging
debug info from fultiple source files.
