Package: gcc-bpf
Version: 14.2.0-1+1
Severity: normal
Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
i noticed that as soon as i enable the -g option to bpf-gcc the builds are non-
deterministic.
* What exactly did you do (or not do) that was effective (or
ineffective)?
running repeatedly
bpf-gcc -g -I /usr/include/ -I /usr/include/x86_64-linux-gnu/ zzz.c ; md5sum
a.out
productes different hash every time. replacing 'gcc-bpf' with 'clang -target
bpf'
stabilizes the output. also commenting out the bpf-helpers have positive
effect...
here comes the the simplest zzz.c file that shows the issue:
#include <linux/bpf.h>
#include <bpf/bpf_helpers.h>
void main(){}
* What was the outcome of this action?
different hash every time
* What outcome did you expect instead?
constant hash every time
