I got some symbol output, but not the expected one.
But it shouldn't be to difficult to implement because the DYNAMIC SYMBOL
table above has already the correct symbol.
That's the output I would expect. If you would rather see the longer
form, pipe the output to c++filt.
OK, piping through c++filt works well. As I specified the -C switch (demangle
C++) I would expect that this is demangled too.
But it looks pretty well now :-)
A diff looks like (wthout and with c++filt):
-080483c0 <_ZdlPv@plt-0x10>:
