Segmentation fault in cscope on linux kernel tree

[Chmouel Boudjnah]

Hi,

While using cscope on the Linux Kernel git tree I am getting a segfault while trying to browse the sources.

Here is my script to generate the cscope database (after a clean git clone of the linux kernel tree) :

#!/bin/bash
BASE=/home/kernel
LNX=${BASE}/linux-2.6/
cd /
find $LNX \
-path "$LNX/arch/*" ! -path "$LNX/arch/i386*" -prune -o \
-path "$LNX/include/asm-*" ! -path "$LNX/include/asm-i386*" -prune -o \
-path "$LNX/tmp*" -prune -o \
-path "$LNX/Documentation*" -prune -o \
-path "$LNX/scripts*" -prune -o \
-path "$LNX/drivers*" -prune -o \
    -name "*.[chxsS]" -print >${BASE}/cscope.files
cd ${BASE}
cscope -b -q -k

When launching cscope I am getting a segfault :

Buildingzsh: segmentation fault (core dumped) cscope 1130 20780
cscope: removed files cscope.in.out and cscope.po.outchmouel@paris:/home/kernel$

the core file does not give much :

Let me know if there is anything I can do to help with this issue.

Cheers, Chmouel.
