Case object with fields that inherit from RootObj causes SIGSEGV #23920

z------------- · 2024-08-03T06:52:30Z

Description

This code produces SIGSEGV at runtime:

type
  Date = object of RootObj # no bug if not `of RootObj`
  Common = object of RootObj
    name: string
    date: Date
  Foo = object
    name: string
    date: Date # no bug if this field is removed
  Bar = object of Common # no bug if not `of Common`, even if its fields are copied here
  ItemKind = enum
    ikFoo
    ikBar
  Item = object
    case kind: ItemKind
    of ikFoo:
      fooVal: Foo
    of ikBar:
      barVal: Bar
 
# also crashes if the below is wrapped in a main proc
let kind = ikBar # no bug if this is const
let item = Item(kind: kind)

Happens on:

devel
2.0.8
1.6.20 with --mm:orc/arc -d:useMalloc

GCC/Clang/-d:release make no difference.

Happens on ORC/ARC. Does not happen on Refc.

#fbc697592 ➡️ 🐛

Diagnostics

andreas rumpf introduced a bug at 2022-10-09 11:44:02 +0200 on commit #fbc697592 with message:

threaded alloc (#20492)

* allocator: catch up with multi-threading techniques
* removed the global thread lock
* more atomics for fun and profit
* added important sysAssert
* stats remain thread local and don't have to be atomic
* undo split chunk optimizations in the hope it makes the CI happy

The bug is in the files:

lib/system/alloc.nim
lib/system/atomics.nim
lib/system/threads.nim

#fbc697592 ➡️ 🐛

Diagnostics

andreas rumpf introduced a bug at 2022-10-09 11:44:02 +0200 on commit #fbc697592 with message:

threaded alloc (#20492)

* allocator: catch up with multi-threading techniques
* removed the global thread lock
* more atomics for fun and profit
* added important sysAssert
* stats remain thread local and don't have to be atomic
* undo split chunk optimizations in the hope it makes the CI happy

The bug is in the files:

lib/system/alloc.nim
lib/system/atomics.nim
lib/system/threads.nim

oh, shit. I made a mistake. I meant to test -d:useMalloc
