Hi Bastian, thanks for having a look! In the upstream ticket Matthias has figured out that the root cause is the lack of the gcc-multilib package, which conflicts with the cross-compilers, which are installed on the affected systems. I believe that this, in turn, is a very old issue, which is not going to go away anytime soon. I tried to upgrade to debian 13, and with it I get better diagnostics from the gcc's configure: configure: error: I suspect your system does not have 32-bit development libraries (libc and headers). If you have them, rerun configure with --enable-multilib. If you do not have them, and want to build a 64-bit-only compiler, rerun configure with --disable-multilib. So we can close this bug. Best regards, Ilya
