With the gjs upstream hat, I have sadly to say that this is probably
something expected: gjs eavily uses complex templates to generate code
all over the places, and such generated code is all kept in memory by
g++ (and any other c++ compiler at the date I think), thus I don't think
it's an anomaly. I suppose compilers could do some local caching but I'm
not aware of a way of doing that.<br/><signature id="local-ef604057-d194"></signature>
