Public bug reported:
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 ${BASE}
cscope -b -q -k
When launching cscope I am getting a segfault :
Buildingzsh: segmentation fault (core dumped) cscope
1130
20780
cscope: removed files cscope.in.out and [EMAIL PROTECTED]:/home/kernel$
the core file does not give much :
[EMAIL PROTECTED]:/home/kernel$ gdb /usr/bin/cscope core

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