Description
Apparently Processing, during the analyses starting from layers in a CRS with +towgs parameters (e.g. 23030) creates outputs with a similar projection, but without the parameters; a custom CRS is thus created, and the output does not align with the input.
This happens at least with GRASS and R backends.

History
#1 Updated by Giovanni Manghi over 10 years ago
- Affected QGIS version changed from 2.2.0 to master
- Priority changed from Normal to Severe/Regression
- Target version set to Version 2.4
Confirmed here on master/ubuntu.
This is certainly a regression.
PS
It does not happen only for CRSs that may exist in two version, one with towgs84 and one not (ex: 3003 and 102091), but happens with all CRSs: in one original CRS has no equivalent version without towgs84 then the result will be a layer with a custom CRS automatically created by qgis.

Hi all,

For example v.select
