Summary: Segmentation fault launching the valgrind
Classification: Developer tools
Product: valgrind
Version: 3.22.0
Platform: Other
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: memcheck
Assignee: jsew...@acm.org

Target Milestone: ---
SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug
symbols.
See

STEPS TO REPRODUCE
1. Just launch valgrind: valgrind --tool=memcheck --leak-check=full
--show-leak-kinds=all -v <application>
SOFTWARE/OS VERSIONS
Linux/OPENWRT.
Using 3.22 valgrind.
arch all 1
arch noarch 1
arch mipsel_24kc 10
ADDITIONAL INFORMATION
I tried using valgrind on ARM and it works perfectly. But on mipsel, i can't
use it.

==15521== TO CONTROL THIS PROCESS USING vgdb (which you probably

==15521== TO DEBUG THIS PROCESS USING GDB: start GDB like this
