From: Francis De Brabandere <francisdb@gmail.com> CSng / CDbl / CDate values vs BSTR string-compare against CStr on Windows rather than coercing the BSTR to a number. Without literal tracking we can't make this conditional, so apply it unconditionally — it's correct for the common non-literal case (e.g. "abc" = CDbl(5) returns False, no error). The bare-literal counterpart ("abc" = 0.5) stays todo_wine pending literal tracking. --- dlls/vbscript/interp.c | 20 ++++++++------ dlls/vbscript/tests/lang.vbs | 53 ++++++++++++++++++++---------------- 2 files changed, 42 insertions(+), 31 deletions(-) diff --git a/dlls/vbscript/interp.c b/dlls/vbscript/interp.c index 823585ccad5..401e0d25c5a 100644 --- a/dlls/vbscript/interp.c +++ b/dlls/vbscript/interp.c @@ -2107,20 +2107,24 @@ static HRESULT interp_imp(exec_ctx_t *ctx) return stack_push(ctx, &v); } +/* Numeric types that take the "BSTR coerces to number, parse failure raises + * type-mismatch" path on Windows.
