Surprised, I verified this with the debugger. On my x86, the entire program is:

(gdb) disass
Dump of assembler code for function main:
0x080483b4 <+0>: push %ebp
0x080483b5 <+1>: mov %esp,%ebp
0x080483b7 <+3>: mov $0x1,%eax
0x080483bc <+8>: pop %ebp
0x080483bd <+9>: ret
End of assembler dump.
(gdb)

Pretty much identical to false(1). Not much danger there.

I tried it: edited the config file /etc/ufw/ufw.conf, and rebooted.
My apache2 web server was blocked, in spite of the entry in
/etc/ufw/applications.d.

So I disabled it again. I'll have to spend more time reading the
documentation. I find the mixture of configuration lines and commands
to be confusing. I don't want to have to enter commands every time I
reboot. The bloody thing creates 31 separate tables, and there's a lot
of structure but not much guidance. Besides that, the stuff in
applications.d has some pretty confusing stuff, which may not even be
used judging by the blocking of apache.
