2. What library installs the `sigacthandler'? It's not a function in

I have just tried psig on on running bash (in another config), and see
that the function that set signals handler for SIGV is indeed:
bash-3.2# pgrep bash
16384
bash-3.2# psig 16384 | grep "^SEGV"
SEGV blocked,caught termsig_sighandler 0
HUP,INT,ILL,TRAP,ABRT,EMT,FPE,BUS,SEGV,SYS,PIPE,ALRM,TERM,USR1,USR2,VTALRM,XCPU,XFSZ,LOST
bash-3.2#
termsig_sighandler() is part bash source code (sig.c) if I am not mistaken.
It is, but that's not what shows up in the call trace. Is `sigacthandler'
part of the Solaris signal trampoline code?
it's part of libc, sigaction() related code as far as I can tell:
http://src.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/lib/libc/port/threads/sigaction.c#283
I am not very familiar with this part of Solaris code to be honest.
