Subject: Fix getCustomDiagID() usage in example code
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=f83451512ecb54410e1ca80a1b3a762051bcc2d1;p=clang

Fix getCustomDiagID() usage in example code

This was setting a bad example. DiagIDs are a limited resource and the message
argument is evaluated as a format string.
