Comment (by ryandesign@…):

 Replying to [comment:3 ryandesign@…]:
 > The El Capitan installer should have removed foreign items from
 protected locations, but apparently it missed /usr/include/malloc.h. I'll
 file a bug report with Apple about this.

 I didn't file a bug report because I was not able to reproduce this
 problem. On a Yosemite system, I placed a malloc.h symlink (and another
 symlink, and a file) in /usr/include, then upgraded to El Capitan. The
 file I placed in /usr/include was moved to the QuarantineRoot, as it
 should have been. The symlinks I created and everything else in
 /usr/include were silently deleted, as they should be. I used the El
 Capitan 10.11.1 installer; maybe an earlier version of the installer had
 this problem but it has since been fixed.
