5.2-alpha completion script source crash

using bash-5.2-alpha causes bash to go 100% and crash.

Gdb reports "Program terminated with signal SIGKILL, Killed.".  bt =
"No stack.".

Earlier version of bash (5.1.4) runs it and exits well.

Compiling it with a safer flag like `-ggdb3 -O -pipe` didn't help.

Thanks for the report. This is the result of needing to clean up parser
state before recursively calling it to parse the command substitution.
