Subject: Silence an annoying GCC warning about use of an uninitialized variable. Even
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=12080d40d567bd4730f1dedbbe9510e50151d8ba;p=clang

Silence an annoying GCC warning about use of an uninitialized variable. Even
making the other switch case unreachable, or sinking the 'continue' into it
doesn't silence this.
