Bug ID: 100438
Summary: `_serialize` macro clashes with user defined
identifiers
Product: gcc
Version: 11.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: heinzisoft at web dot de
Target Milestone: ---
[CryFS](https://github.com/cryfs/cryfs) compiled fine with GCC 10, but it
breaks with GCC 11 because the standard library is now defining a `_serialize`
macro that leaks into user code. When CryFS is trying to call a local
`_serialize` function, the macro is picked instead.
It looks like the macro got introduced here:
