FS#90 - POV-Ray accepts additional patterns after "slope"
The following code is erroneously accepted by POV-Ray (tested with 3.7.0.beta.36):
pigment{
slope { x }
checker
}
The result is a checker pattern.
Apparently there is an EXIT statement missing in the slope-pattern parsing code in parstxtr.cpp.

No beta tester feedback on this for
quite a while, so I consider that good
news.
POV-Ray also erroneously accepts an additional pattern body after pigment pattern, or any pattern preceded with "uv_mapping"; e.g., the following code snippets are also accepted by POV-Ray:
pigment { pigment_pattern { gradient x } checker }pigment { uv_mapping gradient x checker }Underlying error cause is more missing EXIT statements.
fixed with change #4935
