[Trilinos-Users] Zoltan Set_Param( "DEBUG_LEVEL", "0" ) still produces output

Dear all,
We optionally use Zoltan (Trilinos 12.12.1) to partition a graph and we have issues with Zoltan debug output.
If the debug level is set to zero via
std::unique_ptr<Zoltan> zz = ...
zz->Set_Param( "DEBUG_LEVEL", "0" );
the terminal output is still generated
ZOLTAN Load balancing method = 9 (GRAPH)
I found only one place which prints such output: https://github.com/trilinos/Trilinos/blob/f0350316239aaf41e8e6b82378612aaedf9cc72c/packages/zoltan/src/lb/lb_set_method.c#L241-L244 <https://github.com/trilinos/Trilinos/blob/f0350316239aaf41e8e6b82378612aaedf9cc72c/packages/zoltan/src/lb/lb_set_method.c#L241-L244>
if (zz->Proc == zz->Debug_Proc && zz->Debug_Level >= ZOLTAN_DEBUG_PARAMS) {
printf("ZOLTAN Load balancing method = %d (%s)\n",
zz->LB.Method, method_name);
}
And as far as I can tell, the output should be suppressed as ZOLTAN_DEBUG_PARAMS is one:
https://github.com/trilinos/Trilinos/blob/f0350316239aaf41e8e6b82378612aaedf9cc72c/packages/zoltan/src/zz/zz_const.h#L118 <https://github.com/trilinos/Trilinos/blob/f0350316239aaf41e8e6b82378612aaedf9cc72c/packages/zoltan/src/zz/zz_const.h#L118>
I would appreciate any help with suppressing this debug output.
Regards,
Denis.
