Well, obviously it is because
template<typename T>
gmic& gmic::parse(...)
{
...
while (position<command_line.size() && !is_quit) {
loop body with 4000 lines of code (well, including lots of lines
with a few thousand chars, control flow, loops and function calls)
}
...
}
and DF never was good scaling to this kind of code. Maybe not considering
this outermost loop in LIM will fix the slowness... the limit is currently
10000 basic-blocks, maybe a little large when considering non-innermost
loops.
