[Bug middle-end/41264] New: [4.5 Regression] variable-tracking unbelievably slow

[rguenth at gcc dot gnu dot org]

The testcase from PR12392 (I'll attach it again momentarily) now has at -O -g

variable tracking     : 469.04 (89%) usr   0.96 (41%) sys 470.21 (89%) wall 
170235 kB (26%) ggc

the worst-case out of several testcases that show significant compile-time
increases with -O -g.  See
