Comment (by edaskel@…):

 So the issue is basically
 [https://github.com/boostorg/wave/blob/develop/include/boost/wave/cpplexer/re2clex/cpp_re2c_lexer.hpp#L129
 here].  We take the address of the first element of the input and assume
 the rest is lined up in memory behind it.  I'm looking at solutions - the
 most obvious is to make a copy, but Wave already makes one copy of the
 input and I'm not convinced even that should be necessary.
