----------------
this call just sets up the `environ` variables for the `bear_capture_env_t` method, two lines down. that call saves the relevant variables... so, if before execv'ing somebody modify the variables we still have it saved. (by the way `Scons` is the tool which does this.) and when `call_execve` called it recovers from the saved environment.

there is a test against it. (tests/functional/cases/test_create_cdb.py:53)

can you give me details what did you see? what was the test you were running?
