Subject: don't stick an uninitialized 'stat' buf into the stat cache, fill it
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=f1affe6129442b230d3d09b1938e07a7b341a102;p=clang

don't stick an uninitialized 'stat' buf into the stat cache, fill it
with zeros.  This avoids a GCC warning (PR5000)
