Research direction

Start by reproducing the CuTeDSL compilation failure and examining the GDB backtrace, especially the _cutlass_ir.cpython-312-x86_64-linux-gnu.so frames. The report needs a minimal compilation example and environment details before the abort can be localized; done should include identifying the cause and verifying a regression test or confirmed fix.
