Description

I want to create a single buffer by two linestrings, so I create a multilinstring by the linestrings. The linestrings's order will cause the bufferbuild failure,and throw a exception:"depth mismatch at ****".

This has been open for quite some time. At least under postgis I can buffer the geometry fine. Perhaps it depends on side of buffer.

Dismissing this as works for me.
