Hi Chet, Today I compiled bash5 (using default configuration) from the devel branch (f602026a0ce - commit bash-20180316 snapshot) on macOS and found it breaks one of my rc files. After some time of debugging I have the following minimal example to reproduce the problem:
$ bash5 -c 'for i; do echo; done; echo in' bash5: -c: line 0: syntax error near unexpected token `in' bash5: -c: line 0: `for i; do echo; done; echo in' $ Please take a look. -clark
