New comment by balejk on void-packages repository https://github.com/void-linux/void-packages/issues/48758#issuecomment-1949104026 Comment: `# gdb --args su - user` does segfault but `bt` says "No stack". `gdb` also prints "Detaching after fork from child process " -- could that be the reason for the missing backtrace? Unless I'm doing something wrong (`# ulimit -c unlimited; su - user`, works for other binaries), there seems to be no core dumped either.
