We have a bug report with an interrupts file included. (Attached to this email for convenience.) Install that file into place or modify procmeter to use it, and you will be able to reproduce the segfault.
Backtrace:
Program received signal SIGSEGV, Segmentation fault.
Initialise (options=0x0) at stat-intr.c:151
151 while(line2[p2]!=0 && (line2[p2]==' ' ||
line2[p2]=='+'))

$6 = -1212185408
(gdb) p line2
$5 = "0 CPU11 CPU12 CPU13 CPU14 CPU15\000\000 CPU1"
Analysis:
char line2[64];
Maximum line length in interrupts file: 232 QED

(Neil, other bug reports should be opened for any other, unrelated crashes.)

see shy jo, who really doesn't want to maintain procmeter3. I did my time.
