C23 introduced memset_explicit with the same parameters as
|
||||||
|
memset (3 args). New glibc implements it, so the symbol now
|
||||||
|
exists in the global namespace with that prototype, causing
|
||||||
|
“too many arguments” when your code passes 4 args.
|
||||||
|
|
||||||
|
Provide a compatibility macro to address the problem
|
||||||
|

Upstream-Status: Pending
