Hi,

I haven't tested other architectures, so they may be affected as well.

I just built igraph from bookworm-backports on riscv64 with pbuilder,
asking for "-j1" to be passed to dpkg-buildpackage.

The build then started about 2000 parallel processes, leading to a
system load of 500.

I suspect that some calculation for a "-j" parameter ends up computing
an empty string.

Hi Simon,

I think this is just same bug as #1117554, which got fixed in version
1.0.0+ds-1. Note that this is not specific to riscv64.

Thanks, closing this one and adjusting the version information on the
other bug to note that this affects the backported and stable versions.
