Hi folks,
I need help debugging why /bin/bash, /bin/zsh would hang being launched by
Eclipse (v2020-09) -> TM Terminal (v10) -> (shell) on up-to-date Fedora 33.
I am using upstream build Eclipse 2020-09 and the TM Terminal plugin:
1. As root - no problem, TM Terminal can launch /bin/bash
2. As user - both /bin/bash and /bin/zsh hang, (bash at some pselect6() ) call and both do not reach the shell prompt. They are still responsive to SIGHUP.
3. As user - /bin/fish, /bin/sh, /bin/ksh, /bin/tmux(this launches /bin/bash inside) - all work.
For /bin/bash specifically the hang seems to be here:
