Bash Version: 4.3 Patch Level: 42 Release Status: release Description: It seems that mixing process substitution interacting with the terminal and redirections has undesired effects on bash's own sighandlers. Any 'crashing' command with a redirection like: `< <( cat - )` will cause bash to crash. This happens *only* when bash is run directly in the terminal (or tty), when running bash under bash (or under anything else) doesn't seem to allow to replicate the bug. Repeat-By: # THIS IS INTENDED TO CAUSE BASH TO CRASH. Run with care. sleep 10 < <( cat - ) & killall sleep # In general: ./a.out < <( cat - ) # when a.out crashes.
