[harutyuntagushyan8]

I'm building project with emscripten(3.1.47) in which clang version is 18.0.0.
In linking state I got crash with this stacktrace`

Can you share the full em++ command line, and if possible the contents of the rsp.utf8 file passed to wasm-ld? (You can use EMCC_DEBUG_SAVE=1 to have emcc preserve the rsp files that it generates)

[harutyuntagushyan8]

will try to generate rsp.utf file.

[sbc100]

If there is any way you could reduce tat size of the repro, or share the full repro case (you can use -Wl,--reproduce=<file.tar> that would be very useful.

[harutyuntagushyan8]

DOn't understand how I can use -Wl,--reproduce=<file.tar> flag. What's file.tar in my case ?

[harutyuntagushyan8]

Ah to save full log into it. Thanks

[harutyuntagushyan8]

emscripten-core/emscripten#19774
This is exact my case.
Will follow discussions.

[harutyuntagushyan8]

I'm getting same problem with 3.1.47
Seems the problem still exist.

[kleisauke]

Looks like a duplicate of #62243, which is still reproducible on Emscripten 3.1.48.
