On executing the following command
$ grep SIGRTMIN /usr/include/ -r
/usr/include/asm-generic/signal.h:#define SIGRTMIN 32
/usr/include/x86_64-linux-gnu/asm/signal.h:#define SIGRTMIN 32
/usr/include/x86_64-linux-gnu/bits/signum.h:#define SIGRTMIN
(__libc_current_sigrtmin ())
/usr/include/x86_64-linux-gnu/bits/signum.h:#define __SIGRTMIN 32
and checking the source code of glibc-2.19/signal/allocrtsig.c
...
/* Return number of available real-time signal with highest priority. */
int
__libc_current_sigrtmin (void)
{
#ifdef __SIGRTMIN
if (!initialized)
init ();
#endif
return current_rtmin;
}
...
It seems that bash uses the value of current_rtmin

Title:
bash "kill -l" builtin gives wrong numbers for SIGRTMIN+n signals
Status in bash package in Ubuntu:
New
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.
