commit 290348e349e8d56a856f187a08e913f2ed525b3c
Author: Werner Koch <wk at gnupg.org>

    common: Use larger buffer for homedir in case of 64 bit UIDs.
    
    * common/homedir.c (_gnupg_socketdir_internal): Enlarge PREFIX by 6
    bytes for "/gnupg".
    --
    
    The temporary buffer was to short for the extra "/gnupg".  However the
    20 bytes for the UID is large enough for all 32 bit UIDs and would
    only fail (detected) if  a 64 bit UID is used.
