2592. Missing definition for placement allocation/deallocation function

Section: 7.6.2.8  [expr.new]     Status: open     Submitter: Jim X     Date: 2022-04-14

Subclause 7.6.2.8 [expr.new] has multiple references to "placement allocation function" and "placement deallocation function", but those terms are never defined. The term "usual deallocation function" is defined in 6.7.5.5.3 [basic.stc.dynamic.deallocation] paragraph 3:

Possible resolution:

  1. Split 6.7.5.5.2 [basic.stc.dynamic.allocation] paragraph 1 and change it as follows:

    ... The value of the first parameter is interpreted as the requested size of the allocation. A usual allocation function is an allocation function with no parameters after the first or with a single parameter of type std::align_val_t after the first.

    An allocation function can be a function template. ...

Replace "placement allocation / deallocation function" with "not a usual allocation / deallocation function".
