windows newly mingw64 use spdlog header only maybe some problem?

[xiaoyu-githu]

I accidentally found that when using mingw64-builds version 14.2, the header only added spdlog compiles without exception, but the exe will crash when executing. After checking, it is because of calling #include "spdlog/spdlog.h". After multiple verification, it is found that mingw-w64-buils-4.3.5 can be used normally

Duplicate #3100, #3220

You can avoid this problem with SPDLOG_NO_TLS macro (#3220 (comment)).

I'm sorry. I'm not good enough. I'm using it like this, because I'm only using headers, and I just tried to put in common.h ```C
#ifndef SPDLOG_NO_TLS
#if (defined(_MSC_VER) && (_MSC_VER < 1900)) || defined(__cplusplus_winrt)
#define SPDLOG_NO_TLS 1
#endif
#endif

#ifndef SPDLOG_NO_TLS
#if (defined(_MSC_VER) && (_MSC_VER < 1900)) || defined(__cplusplus_winrt)
#define SPDLOG_NO_TLS 1
#endif
#endif
#define SPDLOG_NO_TLS 1
`
Still not working, but I did notice that README.md supports Windows (msvc 2013+, cygwin)
But I use x86_64-14.2.0-release-posix-seh-ucrt-rt_v12-rev0 compile success directly flash back,
I just used Mingw from codeblocks-20.03mingw-nosetup and it worked.So I don't know if that's the reason

If you are going to modify the source code, please uncomment tweakme.h:

spdlog/include/spdlog/tweakme.h

Lines 39 to 46 in 7f8060d

Thank you very much for your help, but it is still not possible. The problem is still there.

I tried to uncomment it.I suspect a compiler problem because I only used
#include "spdlog/spdlog.h" in the header file main.hpp
and spdlog::info("Hello world!") in the source file main.cpp.

If I use this it would be okay:

Sounds like a compiler bug.
