And yes, this looks like a dup to PR36439 to me as well.

Some more info:
HEAD seems to be much faster here (10m30s).
The author uses -fno-tree-pre in gmic (which has a lot of the same code),
not sure whether it helps significantly.

Preprocessed file, as desired. (bzip2ed, as it's too large otherwise.)

Hours is excessive alright.
Unfortunately, there are a couple of things missing to reproduce your problem.
There has to be at least a test case (preprocessed source), and the output of
gcc when you compile the test
