Could you share disassemble of shrink_zone() ? In my environ. 00000000000115a0 : 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 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...
