I tried to bisect, but to my surprise could not find the associated commit.
The only difference was that for bisecting I used another compiler (gcc 4.8.4),
while I otherwise use the version 6.1.0.

So I rebuild lyx with gcc4.8, the error is gone.

Now trying with gcc5.3 ... error.

What are the differences between gcc5.3, 6.1 and 4.8?
gcc4.8  Compiler does not support std_regex, flag = "--std=c++11"
gcc5.3  Compiler supports std_regex, flag = "--std=c++14"
gcc6.1  Compiler supports std_regex, flag = "--std=c++14"

What would be nice is to understand what is the regex:es features that are different between std::regex and boost:regex.
