<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Coverity noted that some of code for message catalog lookup uses some pointer values after they are freed. Even though the use in question is a simple equality comparison against a different (valid) pointer, it is still undefined behavior according to the C (and C++) language specs and is therefore liable to cause miscompilation and who knows what other kinds of problems.
This code is not normally enabled, normally a code path that supports variable-length arrays is active, which is not susceptible to this bug.
Since VLAs are not supported even in current C++ versions, making VLA support mandatory is not feasible, so instead I opted to move the pointer comparisons to a point in the code where the comparison is valid, and then use the saved result later.
I have also reported the bug to GNU Gettext, since upstream still has the error. It is GNU Gettext bug 47847.</pre>

I also tested with the changed code path forcibly enabled by disabling VLA support, and things still seemed to work.
There's not a lot of autotests to choose from, but the KLocalizedString test still passed.</pre>
