env_attr_lookup call env_attr_walk with
callback = regex_callback.
In env_attr_walk
attributes = strchr(entry_cpy, ENV_ATTR_SEP)
will return NULL if ENV_ATTR_SEP is not found.
In the aftermath regex_callback may call
strlen(attributes)
with a NULL value which will lead to a failure.
The problem was indicated by scan-clam.

If the entry is not found in the env .flags, then look in the static
one. This allows the env to override the static definitions, but prevents
the need to have every definition in the environment distracting you.
