config(8) dumps core

[Michael Moll]

Hi All,

after upgrading a FreeBSD/sparc64 machine from CURRENT sources of 3rd
March to ones of 28th April config(8) doesn't work correctly anymore:

server01# config -x /boot/kernel/kernel
options CONFIG_AUTOGENERATED
ident   GENERIC
machine sparc64
cpu     SUN4U
[...]
device  fwe
device  fwip
device  dcons
device  dcons_crom
Assertion failed: (r != '\0' && ("Char present in the configuration " "string mustn't be equal to 0")), function kernconfdump, file /usr/src/usr.sbin/config/main.c, line 721.
Abort (core dumped)

A backtrace does not bring up anything useful:
(gdb) bt
#0  0x0000000040580668 in kill () from /lib/libc.so.7
#1  0x00000000404b6be0 in abort () from /lib/libc.so.7
#2  0x000000004056848c in __assert () from /lib/libc.so.7
#3  0x0000000000104064 in ?? ()
Previous frame identical to this frame (corrupt stack?)
(gdb)

Any ideas on this?

Kind Regards
