Can't the step size be a value-dependent expression like a template

Jason, I'm not sure. The standard says:
"The conditional-expression in a simd-linear-step shall either
satisfy the requirements of an integer constant expression, or
be a reference to a variable with integer type."
I take this to mean, an integral expression or a plain old variable. Is
this the case, Balaji?
Right. An integral constant expression can be value-dependent.
If this is what you're asking, and the above standardeese allows it,
then we have a problem, because the code parsing the "j" in the linear
clause uses cp_parser_id_expression() which gets horrendously confused
with the colon, expecting a '::'.
Sounds like you need to turn off parser->colon_corrects_to_scope_p when
parsing the pragma arguments.
