Can't confirm since the patch can not be applied to 4.6.

(Even though the branch is dead already..)

85%+ of the time is spent in "var-tracking dataflow". This may just be a

duplicate of #54402 but the testcase there is different.

Is this better after the patch for var-tracking that I just checked in?  (I'm

not sure it's related, given that this is reported against 4.6.3, which didn't

have the compile-time regression that the patch addressed, but I thought I'd

ask just to be sure)
