Please include the complete backtrace with any bug report. See <file:///usr/share/doc/gcc-11/README.Bugs> for instructions. Even if import <span> is replaced with #include <span>, the sheer presence of span.gcm leads to an ICE when compiled with -fmodules-ts. The solution is to use the include and remove the gcm file altogether.But this means that there is no way of importing <span> as a module. ^ permalink raw reply [flat|nested] 7+ messages in thread
