Bug 143195 – baselayout-1.12* segfaulting at boot

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description jannis 2006-08-08 04:06:31 UTC]

Preface: I am talking about my unstable/testing-system here. Please don't slay me for my CFLAGS and for using such unstable software such as reiser4, gcc4.X ... it's for finding errors!

After I upgraded to baselayout 1.12.4-r1 my system got a segfault on boot. Here's kinda "screenshot": http://kripton.kripserver.net/pix/screenshot.jpg (Sorry, can't get this thing logged as text)

I don't know exactly why this happens but when I enter my root-pw and revert baselyout to 1.11.15-r3 my machine did boot again. Upgrading baselyout again threw up the same error.
Right now I reverted baselayout and rebooted to post this bugreport.

I've checked my RAM several times with memtest86+-1.65 and it didn't find any errors (I didn't have any problems with my RAM in the past) and I emerged baselayout-1.12.4-r1 with CFLAGS="-O0" and it didn't help either.

Here's my emerge --info:

the problem is, the place where the code is segfaulting is in *bash* code, not C code that we wrote

you could try rebuilding bash with CFLAGS=-O0 but really there's no way for us to debug this

Compiling bash with CFLAGS="-O0" doesn't help......
