      encoding/gob: error out instead of panicking on nil dereference · 0a2a64d8
      Emmanuel Odeke authored 
      Do not panic when we encounter nil interface values which are
invalid values for gob. Previously this wasn't caught yet
we were calling reflect.*.Type() on reflect.Invalid values
thereby causing panic:
  `panic: reflect: call of reflect.Value.Type on zero Value.`
which is a panic not enforced by encoding/gob itself.
We can catch this and send back an error to the caller.

Fixes #16204

      runtime: increase malloc size classes · 14e59511
      Dmitry Vyukov authored 
      When we calculate class sizes, in some cases we discard considerable
amounts of memory without an apparent reason. For example, we choose
size 8448 with 6 objects in 7 pages. But we can well use object
size 9472, which is also 6 objects in 7 pages but +1024 bytes (+12.12%).

Increase class sizes to the max value that leads to the same
page count/number of objects. Full list of affected size classes:

class 36: pages: 2 size: 1664->1792 +128 (7.69%)
class 39: pages: 1 size: 2560->2688 +128 (5.0%)
class 40: pages: 3 size: 2816->3072 +256 (9.9%)
class 41: pages: 2 size: 3072->3200 +128 (4.16%)
class 42: pages: 3 size: 3328->3456 +128 (3.84%)
class 44: pages: 3 size: 4608->4864 +256 (5.55%)
class 47: pages: 4 size: 6400->6528 +128 (2.0%)
class 48: pages: 5 size: 6656->6784 +128 (1.92%)
class 51: pages: 7 size: 8448->9472 +1024 (12.12%)
class 52: pages: 6 size: 8704->9728 +1024 (11.76%)
class 53: pages: 5 size: 9472->10240 +768 (8.10%)
class 54: pages: 4 size: 10496->10880 +384 (3.65%)
class 57: pages: 7 size: 14080->14336 +256 (1.81%)
class 59: pages: 9 size: 16640->18432 +1792 (10.76%)
class 60: pages: 7 size: 17664->19072 +1408 (7.97%)
