To inspect an array of function pointers, I would expect to be able to do
(gdb) p *(void(**)(void))$ops@8
but this gives
A syntax error in expression, near `*)(void))$ops@4'
This can be worked around using the more obtuse cast
p (void(*)(void))*(void**)$ops@8
The need for such shenanigans is more with C++ since x/8a $ops does not pretty-
print the addresses, but the cast should work.
Arch Linux x86_64, kernel 2.6.31, gcc-4.4.2, gdb 7.0

An easier workaround is {void (*)(void)}$ops@8 (or just {void (*)()}$ops@8
since the argument list is ignored anyway).

Excellent, I was not aware of {type}. It makes this issue almost irrelevant.
