A bit OFF TOPIC.
Could you share disassemble of shrink_zone() ?
In my environ.
00000000000115a0 <shrink_zone>:
115a0: 55 push %rbp
115a1: 48 89 e5 mov %rsp,%rbp
115a4: 41 57 push %r15
115a6: 41 56 push %r14
115a8: 41 55 push %r13
115aa: 41 54 push %r12
115ac: 53 push %rbx
115ad: 48 83 ec 78 sub $0x78,%rsp
115b1: e8 00 00 00 00 callq 115b6 <shrink_zone+0x16>
115b6: 48 89 75 80 mov %rsi,-0x80(%rbp)
disassemble seems to show 0x78 bytes for stack. And no changes to %rsp
until retrun.
I may misunderstand something...
Thanks,
