AFAIR, the ECMAScript regexes are a proper subset of PCRE whereas there

default for <regex>, so maybe it is better supported across compilers.
This makes ECMAScript the simplest for a transition.
Is the bug there with g++ 6? I remember Georg saying that the early
implementations of <regex> in gcc were buggy.
The first usable version is in 4.9.0, so <regex> in gcc should not be a
problem anymore on any recent distro.
On the other hand I do not remember that dynamically created regexes
were reviewed for adaptation to ECMAScript so maybe there is indeed
something to change, although not (?:.
Dear Georg, do you remember the same?
I do not remember any review of dynamically generated regexes. I also have
to admit that dynamically generated regexes are too complicated IMHO (too
many levels of indirection). Unfortunately I do not understand the advanced
search well enough to propose a better solution.
Thank you Georg for the reply.
Another solution if nobody finds how to fix it is to disable
std::regex until one does.
