 We carry a small patch to `execute_cmd.c` (see `patches/bash-exec-wrapper.patch`) that adds support for `EXEC_WRAPPER`. The original commit message is “add support for BASH_EXEC_WRAPPER” and the patch applies cleanly to `a8a1c2fac029404d3f42cd39f5a20f24b6e4fe4b` from https://github.com/bminor/bash. To rebuild manually:
