There seems to be some issue with signed/unsigned sizes and conversions:

  .../gcc/12.3.1-40d504be6370b5a30e3947a6e575ca28/include/c++/12.3.1/bits/char_traits.h:435:57: warning: 'void* __builtin_memcpy(void*, const void*, long unsigned int)' accessing 9223372036854775810 or more bytes at offsets [2, 9223372036854775807] and 1 may overlap up to 9223372036854775813 bytes at offset -3 [-Wrestrict]

9223372036854775807 is 0x7FFFFFFFFFFFFFFF, 9223372036854775810 is 0x8000000000000002, 9223372036854775813 is 0x8000000000000005

I don't think we have such large buffers...

fwyzard commented 8 months ago

The line gcc complains about in the first error is

                rtCheck<TApi, TThrow>(error, ("'" + std::string(cmd) + "' returned error ").c_str(), file, line);

What is wrong with it ?

makortel commented 8 months ago

The std function in question is (I added a comment to highlight the line 435)

  template<>
    struct char_traits<char>
    {

    // ...

      static _GLIBCXX20_CONSTEXPR char_type*
      copy(char_type* __s1, const char_type* __s2, size_t __n)
      {
        if (__n == 0)
          return __s1;
#if __cplusplus >= 202002L
        if (std::__is_constant_evaluated())
          return __gnu_cxx::char_traits<char_type>::copy(__s1, __s2, __n);
#endif
        return static_cast<char_type*>(__builtin_memcpy(__s1, __s2, __n)); // <------ line 435
      }

Given the large numbers, smells like a compiler bug.

chillenzer commented 5 months ago

See https://github.com/alpaka-group/alpaka/pull/2295 should soon be resolved in latest develop branch.

                rtCheck<TApi, TThrow>(error, ("'" + std::string(cmd) + "' returned error ").c_str(), file, line);

Looking at it again: is the temporary returned by c_str() guaranteed to be valid in this case ?

fwyzard commented 4 months ago

Answering myself: yes, it should be fine.

makortel commented 2 months ago

(just came across the warnings in a local area) Would it be worth for us to cherry-pick https://github.com/alpaka-group/alpaka/pull/2295? Or we wait for the Alpaka 1.2 and upgrade there in 14_2_X? (although that would leave the warnings in 14_1_X build logs)

fwyzard commented 2 months ago

We can cherry pick it, I think we are already using a dedicated branch anyway.
