Source: fenics-dolfinx Followup-For: Bug #1096624 Control: tags -1 ftbfs There is a fair change this is not a gcc-15 bug, nor even a bug at all. It's more likely to be a nanobind inconsistency.
All nanobind clients need to be rebuilt at the same time to maintain interoperability. cf. dolfinx-mpc Bug#1096535 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1096535
