Package: mawk
Version: 1.3.4.20250131-1
Severity: normal

Usertags: arm64
Running `mawk 'BEGIN {print rand()}'` on Debian Trixie on arm64,
produces the same results. It is expected (and documented) that srand()
is called implicitly. And on Bookworm or on amd64, this works as
expected. Easy to reproduce using docker:
```
$ docker run -it --rm --platform linux/arm64 debian:trixie sh -c 'for i in 1 2
3 4; do mawk "BEGIN {print rand()}"; sleep 1; done'
0.118709
0.118709
0.118709
0.118709
```
```
$ docker run -it --rm --platform linux/amd64 debian:trixie sh -c 'for i in 1 2
3 4; do mawk "BEGIN {print rand()}"; sleep 1; done'
0.301452
0.968917
0.975551
0.0758413
```
```
$ docker run -it --rm --platform linux/amd64 debian:bookworm sh -c 'for i in 1
2 3 4; do mawk "BEGIN {print rand()}"; sleep 1; done'
0.133928
0.991352
