Hi all!
Thanks to all those who helped me, those problems I had before have been
solved. Frederik, specially, who helped me from the beginning to the end. I am
also happy to help those who had the same problem and could not solve it.
The last thing I want to say is that I'm an illiterate
Did you remember to disable incremental linking?
Last time I tested it, LINK.EXE did work, but if you had incremental linking
enabled (I think it’s on by default?) then it inserts random padding into the
Objective-C runtime’s metadata sections, which corrupt various things.

I tried adding /INCREMENTAL:NO, but the issue persists.
Also the documentation says that incremental linking is disabled when the
output file doesn’t exist, which is confirmed by this log after deleting the
.exe:

Alright.
win10 => 19044
clang version => 16.0.0
gnustep-*, libobjc2, etc.. => https://github.com/gnustep/tools-windows-msvc
Thanks again.

Thanks, I reproduced the issue here. It turns out using the Microsoft linker
causes this issue, but using LLD works fine. I’m not sure why or since when
this is, as using link.exe definitely worked for me at one point, but now using
either VS 2019 or 2022 causes this crash as soon as
I am no Windows expert but I remember that for some compilers we needed special
symbol handling there. We use the macro GS_EXPORT_CLASS there which boils down
to some __declspec(dllexport) declarations on classes. Not sure whether this
would also be needed for a class that is only locally used.
Sure! The following is it:
* thread #1, stop reason = Exception 0xc005 encountered at address
0x7ffcec4e1048: Access violation reading locatio
n 0x
* frame #0: 0x7ffcec4e1048 objc.dll`objc_msgSend + 40
frame #1: 0x7ff645cc1154 abc.exe
frame #2: 0x7ff645cc142c abc.exe
Can you send the backtrace of the crash ("bt" in LLDB)?

Hi all! I seem to have found the problem.the problem is that the user-defined

I know this is an error usually caused by null pointers, but my code has been
tested to be fine under linux. When I compile and run my program on windows
using tools-windows-msvc provided by gnustep, I get this error, and I suspect
that it is caused by one of gnustep's own libraries on windows,
Just a note

this is not a nil pointer but an uninitialized variable.
Try: NSString *mystring = nil; // nil pointer
Nevertheless it could be the reason why "loserist" sees his exception,
My guess is a nil pointer was accessed.
I made this test program to see what would happen if a nil pointer was accessed:
#include
int main(int argc, char *argv[]) {
NSString *mystring;// nil pointer
NSLog(@"mystring: %@", mystring); // crash here
}
The result was
Hi all! I want to get help from you.Thank You.
