From: Francis De Brabandere <francisdb@gmail.com> VT_RESERVED is set on numeric literal pushes (interp_int / interp_double / interp_date) and stripped at every boundary that isn't the comparison consumer; var_cmp dispatches on the flag so BSTR vs literal numeric goes through numeric coercion (error 13 on parse failure) while BSTR vs non-literal numeric uses string compare against CStr(numeric). VT_BOOL is handled in the same branch with hardcoded "True"/"False" since VarBstrFromBool yields "-1"/"0". Const references are inlined at compile time, so a new OP_strip_reserved opcode is emitted after the inlined expression to clear the flag and make Const behave like a variable read. --- dlls/vbscript/compile.c | 18 +++-- dlls/vbscript/global.c | 5 ++ dlls/vbscript/interp.c | 104 ++++++++++++++++++++++++--- dlls/vbscript/tests/lang.vbs | 134 ++++++++++++++++++++--------------- dlls/vbscript/vbdisp.c | 3 + dlls/vbscript/vbscript.h | 7 ++ 6 files changed, 197 insertions(+), 74 deletions(-) diff --git a/dlls/vbscript/compile.c b/dlls/vbscript/compile.c index 16e661c98ff..5ae679d7828 100644 --- a/dlls/vbscript/compile.c +++ b/dlls/vbscript/compile.c @@ -510,8 +510,13 @@ static HRESULT compile_member_call_expression(compile_ctx_t *ctx, member_express expression_t *const_expr; const_expr = lookup_const_decls(ctx, expr->identifier, TRUE); - if(const_expr) - return compile_expression(ctx, const_expr); + if(const_expr) { + HRESULT hres; + hres = compile_expression(ctx, const_expr); + if(FAILED(hres)) + return hres; + return push_instr(ctx, OP_strip_reserved) ?
