Subject: Kconfig: conf segfault (with invalid kconfig contents)
Date: Tue, 23 Oct 2007 22:14:01 -0500 [thread overview]
Message-ID: <20071024031401.GA13376@lixom.net> (raw)
Hi,
Sorry, no patch, just a bugreport. :)
I did a mistake in some Kconfig changes (locally) and got a segfault
from conf:
#0 0x10005fe0 in sym_check_deps ()
#1 0x10005f40 in sym_check_expr_deps ()
#2 0x1000605c in sym_check_deps ()
#3 0x1000f3f4 in conf_parse ()
#4 0x10003824 in main ()
The way to reproduce is simple. I just added the equivalent of this
to arch/powerpc/Kconfig:
---
config TEST1
bool
depends on TEST2 && PCI
select TEST2
config TEST2
bool
---
Neither TEST1 nor TEST2 exists in the existing .config when I run make
oldconfig to reproduce.
It's clearly invalid in that it depends on what it selects, but it should
just abort instead.
