In seems there is an issues with the step into command at MacOS port of gdb. As workaround you could set breakpoint at the function start to step into the template function:

(gdb) b f
Breakpoint 1 at 0x1000015ab: file ./gdb_tmpl.cpp, line 6.
(gdb) run
Starting program: /Users/vershov/tmp/tests/a.out 

Breakpoint 1, f (x=12.300000000000001) at ./gdb_tmpl.cpp:6
6       std::cout << "In f:" << std::endl;

Also, you could disassemble it, just use correct command:

(gdb) disass f
No symbol "f" in current context.
(gdb) disass f
Dump of assembler code for function f(double):
