Avoid an allocation in modelling Std C functions to improve the performance.
I guess i was planning for C++ support here, but never reached that far.
Is it an actual performance problem? Cause i think i did somehow test the checker for performance regressions and it seemed all good.
I did not measure it. Just spotted by skimming through the code. I think, this is not a performance problem, but since it is easy to avoid the allocation and this codepath might be executed for every call, it might be worth to fix this.
