So when the edge is insert to the heap we see:
Badness calculation for app_disable/164630 ->
_Z11app_disablev.part.30/166180
size growth 6, time 16.000000 unspec 216.000000
Wrapper penalty. Increasing growth -4 to 30
-0.000709: guessed profile. frequency 0.000000, count 195 caller count
66781966 time w/o inlining 5.000000, time with inlining 5.000000 overall growth
-4 (current) -4 (original) 900 (compensated)
Adjusted by hints -0.002838
and when the ICE happens:
