commit a2dc2a69d6b4a3706ea3b3ac1b05c250ae8c7be3
Author: Julien Cristau <jcristau@debian.org>

    Fix wrong Xfree in XListFonts failure path
    
    'ch' gets moved inside the allocated buffer as we're looping through
    fonts, so keep a reference to the start of the buffer so we can pass
    that to Xfree in the failure case.
    
    Fixes: commit 20a3f99eba5001925b8b313da3accb7900eb1927 "Plug a memory leak"
