Dear Maintainer,

When compiling qtwebengine-opensource-src on mipsel, I get this error:

during RTL pass: split2
../../3rdparty/chromium/media/filters/source_buffer_stream.cc: In member function
'void media::SourceBufferStream<RangeClass>::Remove(base::TimeDelta, base::TimeDelta, base::TimeDelta) [with RangeClass = media::SourceBufferRangeByPts]':

It looks like it is already fixed upstream:

https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=273174

So please backport that change to the Debian package.
