Bug#1106083: scilab: FTBFS: autobuilder hangs when using the kernel of trixie

[Santiago Vila]

For the record, I've put more recent failed build logs in the same place as before:

https://people.debian.org/~sanvila/build-logs/202507/

Based on that, this is what we know:

- It fails the same when using 6.12.33+deb13-cloud-amd64.
- It fails the same regardless of using unshare or the old schroot backend.

Thanks.
