--- Comment #1 from Steven Schveighoffer ---
The underlying issue is that `std.internal.cstring.tempCString` returns a
`null` pointer if the input string is an empty string with a null pointer.
This is surprising, and seems to have been done as a hack to work around issue
14980
I would not expect to get a null pointer when passing in an empty string, I'd
expect an empty string. This has a seemingly "unforseen" effect on code that is
accepting of a string, and blindly passes to `tempCString` for calling a C lib
-- if the library function doesn't handle null pointers, or handles them
differently than non-null empty strings, then it may crash or do something
unexpected.
The Linux `getenv` function is crashing on the null pointer (BTW, this does not
happen on MacOS).
