+/* I'm running gdb 3.4 under 386/ix 2.0.2, which is a derivative of AT&T's
+Sys V/386 3.2.
+
+On some machines, gdb crashes when it's starting up while calling the
+vendor's termio tgetent() routine.  It always works when run under
+itself (actually, under 3.2, it's not an infinitely recursive bug.)
+After some poking around, it appears that depending on the environment
+size, or whether you're running YP, or the phase of the moon or something,
+the stack is not always long-aligned when main() is called, and tgetent()
+takes strong offense at that.  On some machines this bug never appears, but
+on those where it does, it occurs quite reliably.  */
