Bug ID: 385127
Summary: Segfault when loading the assembly of strcmp
Product: kcachegrind
Version: 0.8.0kde
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: josef.weidendor...@gmx.de
Reporter: elouan.pig...@gmail.com
Target Milestone: ---
Hi,
I was looking at kcachegrind, to have a look i compilled the most basic empty C
program without any library that looks like this :
int main(void)
{
return 0;
}
I tried compilling it using both gcc and clang, adding the "-g" option, and i
used valgrind with "--dump-instr=yes --collect-jumps=yes --tool=callgrind"
The issue is when trying to have a look at the bottom right "Machine Code" tab,
on the "strcmp" function, kcachegrind segfault directly.
I don't really know what i can add to help, hmm apparently i can't add multiple
attachements when submitting a bug, what i'm gonna do is upload the related
files...
uname -a : Linux dev 4.12.13-1-ARCH #1 SMP PREEMPT Fri Sep 15 06:36:43 UTC 2017
x86_64 GNU/Linux
valgrind --version : valgrind-3.13.0
gcc : 7.2.0
kcachegrind : 0.8.0kde (installed using pacman )
Here is a archive with the callgrind.out, the a.out and the code+binary used
when segfault : http://s000.tinyupload.com/?file_id=41787805261408517736
Feel free to ask for more if you can't reproduce it, i might compille
kcachegrind with debug flags and so on when i'll have time like tomorow or
something..
Have a good day !
