Description
Verilator version: Verilator 3.812 2011/04/06 rev verilator_3_811-18-ga20b4f2
When a task with vector input arguments is exported as a DPI call, gcc fails with the complaint
error: invalid operands of types 'int' and 'const svBitVecVal*' to binary 'operator&'
when compiling V<base>__ALLcls.cpp. The problem is that the argument is passed by reference, but not dereferenced before assignment. Run the example with "sh doit.sh" to see the problem.

Your patch was close; it only needed to be done on bit vector types not non-vector types.
Fixed in git for 3.813.
