Issue #20892 has been reported by byroot (Jean Boussier). ---------------------------------------- Bug #20892: `ObjectSpace.dump` can produce broken JSON for classes with temporary names https://bugs.ruby-lang.org/issues/20892 * Author: byroot (Jean Boussier) * Status: Open * Backport: 3.1: DONTNEED, 3.2: DONTNEED, 3.3: REQUIRED ---------------------------------------- ```ruby puts ObjectSpace.dump(Class.new.tap { |c| c.set_temporary_name('" little boby table') }) ``` Produces the following JSON: ```json { "address":"0x120bea980", "type":"CLASS", "shape_id":2, "slot_size":160, "class":"0x120bea840", "variation_count":0, "superclass":"0x1041ffd38", "name":"" little boby table", "references":["0x1041ffd38", "0x123e71a98"], "memsize":192, "flags":{"wb_protected":true} } ``` Notice how the `name` property is broken. This only impacts 3.3.x, as that's when `set_temporary_name` was introduced, before that, it was impossible to assign a name that would cause such bug. -- https://bugs.ruby-lang.org/
