X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fa696d0a06b198b4d85964c6a31f40486e7b6348;p=dealii.git

New tensor_product_manifold_03 test

This test exposes the bug and currently fails.

It attempts the assignment of a TensorProductManifold object, to a
Triangulation object, in an inner visibility scope. Once the execution
flows leaves the inner scope, the local manifold objects are destroyed
triggering a subscriptor error.
