[Bug 1433155] Re: bash "kill -l" builtin gives wrong numbers for SIGRTMIN+n signals

[Explorer09]

This is not a bug! It's expected behavior!
The SIGRTMIN number you quoted from /usr/include/asm/signal.h is a kernel minimum number of real-time signal, which is usually used by pthread library and not available for user apps.

Both of these two Stack Exchange questions have explained this:

http://unix.stackexchange.com/questions/155829/why-does-kill-l-not-list-signal-numbers-of-32-and-33
http://stackoverflow.com/questions/12680624/what-has-happened-to-the-32-and-33-kill-signals

Now, should this "bug" be closed?

Title:
  bash "kill -l" builtin gives wrong numbers for SIGRTMIN+n signals

Status in bash package in Ubuntu:
  Confirmed

Bug description:
  The command "grep SIGRTMIN /usr/include/ -r" gives me

  /usr/include/asm/signal.h:#define SIGRTMIN      32

  and a bunch of other defines with the same value. But if I ask bash's
  "kill" builtin via "kill -l", I get "34) SIGRTMIN". What's
  interesting, there's actually no number 32 listed at all. Number 34
  goes right after 31, where the right 32 should appear. The other names
  defined via SIGRTMIN are also wrong.
