It has never been tried before, so have no idea how close it is of working.

You should run inside a debugger and see the stack trace when LLVM aborts.
You can also see the LLVM IR by setting the following env var:
GALLIVM_DEBUG=ir
Or dump it to a file by applying this change:
diff --git a/src/gallium/drivers/llvmpipe/lp_state_fs.c
b/src/gallium/drivers/llvmpipe/lp_state_fs.c
index ff78b9d..ab37950 100644

- if (0) {

LLVMWriteBitcodeToFile(gallivm->module, "llvmpipe.bc");
}
