thank you. I didnt know about that.
I added an extra pad arg and I'm still getting weirdness:
p2 = __syscall(197, 0x100000, 4*4096, 7, MAP_ANON, -1, 0, 0);
results in
1947 a.out CALL
mmap(0x100000,0x4000,0x7<PROT_READ|PROT_WRITE|PROT_EXEC>,0x1000<MAP_ANON>,-1,0x7f7f00000000)
vs straight call:
1947 a.out CALL
mmap(0,0x10000,0x3<PROT_READ|PROT_WRITE>,0x1002<MAP_PRIVATE|MAP_ANON>,-1,0)
