Bash Wipes Out DYLD_LIBRARY_PATH on El Capitan

Originator:justatheory
Number:rdar://22807197 Date Originated:2014-09-22
Status:Closed Resolved:Duplicate
Product:OS X Product Version:10.11 Beta (15A278b)
Classification: Reproducible:Always
 
Summary:
I use zsh, but need to use bash scripts. Some of them need to use `LD_LIBRARY_PATH` and/or `DYLD_LIBRARY_PATH`. However, they are not passed through to bash. This emits nothing:

    DYLD_LIBRARY_PATH=test bash -c 'echo $DYLD_LIBRARY_PATH'

 I have no custom `~/.bash*` files.

Steps to Reproduce:
1. Start a terminal session with an account that uses zsh for its shell.
2. Make sure there are no `~/.bash` files
3. Run `DYLD_LIBRARY_PATH=test bash -c 'echo $DYLD_LIBRARY_PATH'`

Expected Results:
Should emit "test"

Actual Results:
Emits a blank line.

Version:
10.11 Beta (15A278b)

Notes:
Interestingly, the same happens when calling zsh:

    DYLD_LIBRARY_PATH=test zsh -c 'echo $DYLD_LIBRARY_PATH' 

It looks like something in the system is mucking with this variable so it doesn't get passed through. Related to call to `setuid()` or `setgid()` as described in rdar://11894054?

Output on Yosemite: 

$ DYLD_LIBRARY_PATH=test bash -c 'echo $DYLD_LIBRARY_PATH'
test
$ DYLD_LIBRARY_PATH=test zsh -c 'echo $DYLD_LIBRARY_PATH'
test

So, is this due to the new "rootless" feature of El Capitan?
