Bingo! In my case, since I'm using Memory Sanitizer I needed to
set MSAN_SYMBOLIZER_PATH rather than ASAN_SYMBOL

Hi Heinrich,
It looks like a bug (or at least an undocumented divergence from GCC) in
Clang/LLVM. Or I couldn't find the documentation for it.
Clang uses 'char *':
https://github.com/llvm/llvm-project/blob/7faf62a80bfc3a9dfe34133681fcc31f8e8d658b/clang/include/clang/Basic/Builtins.def#L583
GCC
It looks like GCC recently moved from 'char *' to 'void *'.
This SO question[1] (4 years ago) quotes the GCC docs
and they had 'char *'.
Maybe Clang hasn't noticed the change.
I'll report a bug.

Hello Martin,
Thanks for the correction!
Then the prototypes that changes from 'char *' to 'void *' in r269082
were not exposed to the user, right?
I guess then those are just internal implementation where GCC did use
'char *'.
Where is the actual prototype exposed to the user declared?
Thanks,
Hi Martin,
I sent you an email, but I received a "delivery failure".
If you're reading this from a list, could you answer, please?
Thanks,

Hi Martin,
Thanks! It's good to learn some GCC internal details :)

This should be fairly well documented. Try these:

Hello,
I'm trying to use clang-format to format source files of a project, nowadays
done with the help of indent.
I'm trying to get an old tradition thing like :
int
myfunction(a, b)
inta;
char *b;
{
...
But, playing with .clang-format file, what I have is always something like :

`strrchr(__FILE__, '/')+1` should get resolved at compile-time whenever you
have optimizations on.

Hi,
I have some benchmarks where I have to use mcmodel=medium, but clang does not
seem to have a flag corresponding to this.
I was wondering if there is recommended way around this.
Greetings,
