To avoid wasting steps/time w/ multiple iterations, you would rather
have the "err_noinfo &&" be a gate to strchr and "err_info &&" be a gate
to virErrorTestMsgFormatInfoOne?

So that the only diffs are:

-        if (strchr(err_noinfo, '%')) {
+        if (err_noinfo && strchr(err_noinfo, '%')) {

and

-        if (virErrorTestMsgFormatInfoOne(err_info) < 0)
+        if (err_info && virErrorTestMsgFormatInfoOne(err_info) < 0)


Tks -
