See attached archive for an example.
When stepping through the program 'main', displaying the symbol
'test' (defined in the shared library 'test.so') gives 
'text variable, no debug info', instead of a type information.
like "{void ()} 0x40013580 <test>".

Moreover, it is not possible to set a breakpoint in that
function. This worked in the previous version of gdb (4.18)
is was using. So I believe this bug was introduced in some
rewriting of the GDB code.
>How-To-Repeat:
make
gdb ./test
break main
r
n
p test
break test
scratch head
>Fix:
I wish I knew how to fix that.
