fix UB when initializing parameterized tests
When running tests built with
-fsanitize=undefined and--disable-optimizations
the sanitizer will emit errors of the following general form:
runtime error: member call on address 0xxxxxxxxx which does not
point to an object of type 'WithParamInterface'
0xxxxxxxxx: note: object has invalid vptr
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ...
^~~~~~~~~~~~~~~~~~~~~~~
invalid vptr
This can be traced to calls to WithParamInterface<T>::GetParam before
the object argument has been initialized. Although GetParam only
accesses static data it is a non-static member function. This causes
that call to have undefined behaviour.
The patch makes GetParam a static member function.
upstream pull request:
https://github.com/google/googletest/pull/1830
The alternative - if the pull request is denied - would be to
modify all parameterized tests to have them derive from
::libvpx_test::CodecTestWith*Params as the first base class.
