Bash Version: 4.4 Patch Level: 12 Release Status: release Description: I was bitten by earlier iterations of case selectors prematurely ending an $() and my actual problem has been patched in the newest release (thanks!). I came across a degenerate case in my testing, though. Repeat-By: foo=$(while true; do case $HOME in /*) echo abs ;; esac; done) bash: syntax error near unexpected token `;;' It works if you replace "true" with "false", or even with ":" (in which case it loops endlessly as it should) Workaround: Use backticks, or don't write degenerate code.
