Giffuni from comment #8) Could you, please, read some code instead of commit messages, before coming with conclusions ? The sizing of exec_map is scaled with number of cpus. It is already pared = down on ILP32 due to KVA exhaustion issues. Even if we assume that the bump is = from 4M to 8M (which is not), it is already quite sensitive for low-KVA machines. On my low-end (8 threads but amd64) desktop machine, I have ~17M reserved f= or the submap. --=20 You are receiving this mail because: You are the assignee for the bug.=
