i hadn't, but i just tried it like so, where Next is basically as Skip described:
cpu% 8c -FTVw -N ps.c
cpu% 8l -N -o 8.ps ps.8
cpu% cp 8.ps /386/bin/ps
cpu% acid /bin/ps
/bin/ps:386 plan 9 executable
/sys/lib/acid/port
/sys/lib/acid/386
acid: new()
1645200: system call _main SUBL $0x48,SP
1645200: breakpoint main+0x3 MOVL $0x1,none+0x2c(SP)
acid: Next()
mischief 1 0:00 0:00 220K Await bootrc
mischief 2 12:39 0:00 0K Wakeme genrandom
<rest of output elided>
1645200: breakpoint main+0xb CMPL argv0(SB),$0x0
<stdin>:3: (error) msg: pid=1645200 startstop: process exited
acid:
Bsrc shows this happens right after ARGBEGIN. maybe that confuses acid?
i should mention now that i am on 9front, but i hope that doesn't matter.
