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? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to bash in Ubuntu. https://bugs.launchpad.net/bugs/1433155 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.
