[comp.unix.ultrix] sigsetmask does not return

mf@ircam.fr (Michel Fingerhut) (10/29/90)

Setup:	DECsystem 5810
	Ultrix 4.0 rev 179
	Vanilla X11.R4

Building epoch-3.2 (public domain extension of emacs to the X window system).

When temacs is 1st invoked, it hangs.  Dbx shows call to sigsetmask(-1) entering
but not returning.  When replaced by POSIX calls, i.e.,
	sigprocmask(SIG_SIGSETMASK, mask, oldmask)
it hangs as well.

Any clues/help?  Thanks in advance,
Michael Fingerhut
