I've tried to reproduce the Erlang FTBFS in qemu (both on malta and loongson-virt machines) and failed to do so. Also, I've found a thread on linux-kernel mailing list, which might be relevant (see [1]). It describes some EFAULT on mips64 which were introduced roughly at the same time when Erlang started to FTBFS. I've run the test they suggested (on qemu on loongson-virt machine). The test program is compiled using gcc-14 (14.2.0-16). The test program aborts on kernels 6.1.0-29-loongson-3 (6.1.123-1) and 6.12.10-loongson-3 (6.12.10-1) The test program does not abort on kernel 5.10.0-30-loongson-3 (5.10.218-1) [1] https://lore.kernel.org/all/mvmplxraqmd....@suse.de/T/ Cheers! -- Sergei Golovan
