I'm using valgrind 3.14.0 from
http://ftp.debian.org/debian/pool/main/v/valgrind/
Cause it's stable version.
I did not compile this application.
Right now i'm trying latest valgrind 3.16.1 and it changed from this:
99.87% (20,675,133B) (heap allocation functions) malloc/new/new[], --alloc-fns,
etc.
->99.87% (20,675,133B) 0xFFFFFFFF: ???
to this (different app, but the only change is from 0xFFFFFFFF to 0x0):
99.82% (46,610B) (heap allocation functions) malloc/new/new[], --alloc-fns, etc.
->99.82% (46,610B) 0x0: ???
Using "(gdb) break malloc" and then "(gdb) bt"produces regular callstack
Also using gdb+vgdb is producing correct backtrace:
(gdb) monitor v.info scheduler
Host stacktrace:
==1543== at 0x5800B148: ??? (in
/home/root/lbolda/vg16/usr/lib/arm-linux-gnueabihf/valgrind/massif-arm-linux)
sched status:
running_tid=1
Thread 1: status = VgTs_Runnable (lwpid 1543)
==1543== at 0x42826: service_main(int, char const**, bool)

Thank you for helping me!

callstack? (arm)
Which version of valgrind are you using ?
You much better should use the last released version (or a more recent GIT
version).
Have you compiled your application with -g ?
In case you debug your native executable with gdb and put a break on malloc, is
gdb backtrace command giving a good stack trace ?
If you then debug using gdb+vgdb your executable running under valgrind, is
then the gdb backtrace correct ?
And when positioned on the break point, what is the output of
(gdb) monitor v.info scheduler
Thanks
Philippe
