Subject: Fix uninitialized variable use bug found by the clairvoyant static analyzer.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=af505c58222a87058fa4ac26cd8da27c141eec42;p=clang

Fix uninitialized variable use bug found by the clairvoyant static analyzer.

Commit::canReplaceText would not initialize its out 'Len' parameter before
returning true and it would be used uninitialized in Commit::replaceText.
