GDB on `gensim` shows that the error comes from a call to `gci.GenerateExecuteBodyFor(body_str, *action);`, so it looks like there are some missing cases in `EmitFixedCode`.
Rebuilding with `-DCMAKE_BUILD_TYPE=DEBUG` + GDB on `gensim` shows that the error comes from a call to `gci.GenerateExecuteBodyFor(body_str, *action);`, so it looks like there are some missing cases in `gensim/src/generators/GenCInterpreter/InterpreterNodeWalker.cpp` function `SSAIntrinsicStatementWalker::EmitFixedCode`, e.g. there should be one for `__builtin_abs64`.
This is completely broken academic code! They must be using an off-tree of part of the tool and forgot to commit.
