I've pushed the fix for this [1]. The only other instance I saw of
LLVMBuildZExt for TypeDatum is in llvmjit_expr.c for "case
EEOP_BOOL_NOT_STEP". I didn't adjust this as it wasn't clear to me
that it was a problem. I expect the value being zero extended there is
either a 0 or 1, so didn't want to risk touching that code if it isn't
broken.
Emmanuel,
You should be seeing it in the next minor releases due around
mid-November. In the meantime, I suggest turning off
jit_tuple_deforming.
Many thanks for reporting this and coming up with the steps and backup
to reproduce the issue.
David
