--- Comment #6 from Benedek <erenon2 at gmail dot com> ---
The following code reproduces this, or a very similar issue:

#define STORE(SECTION, STRING) \
  __attribute__((section(SECTION), used)) \
  static constexpr const char* s[] = { STRING }

void f()
{
  STORE(".custom", "normal_foobar");
}

inline void g()
{
  STORE(".custom", "inline_foobar");
}

template <typename = void>
void h()
{
  STORE(".custom", "template_foobar");
}

int main()
{
  f(); g(); h();
  return 0;
}

$ g++ -std=c++11 section.cpp
section.cpp: error: 's' causes a section type conflict with 's'

GCC 4.8, 5.2, 7.2, and trunk are affected (x86-64, checked on godbolt).
Depending on the compiler version, either the normal and the inline, or the
normal and the function template clashes.

I suppose because of how comdat is handled, they might have slightly different
needs, but it would be really nice to make it easier for the user.

(Clang compiles it fine)
