Comment (by anonymous):

 I'm also seeing this issue with gcc 4.8.4 and boost 1.56 but only when -Og
 is used.

 For me the warnings are reported at the point where lexical cast is used
 rather than in the boost header, so our usual warning suppressions don't
 do anything. I've tried adding the suggested #pragma GCC diagnostic push
 stuff around our include of boost/lexical_cast.hpp but it also has no
 effect.

 The only way I've found to get around it is to disable -Wuninitialized in
 debug builds.
