Dear all,
the attached obvious patch fixes an ICE on a NULL pointer
dereference. We didn't properly check that the types of
expressions are character before referencing the length.
The issue was originally investigated by Steve, so I made
him co-author.
Regtested on x86_64-pc-linux-gnu and push
Dear all,
we hit a NULL pointer dereference when trying to simplify PACK
when the MASK argument was present. The obvious and trivial
solution is to check for NULL pointer dereferences why looking
at the constructor for the ARRAY argument, which we already do
in the case the MASK is not present.
