Experiencing Quartus unexpected error when compiling a partially reconfigurable design

Here is "setup.tcl" content:

define_project top

define_base_revision top

define_pr_impl_partition -impl_rev_name top_pr_alpha \

-partition_name pr_partition \

-source_rev_name top_default

define_pr_impl_partition -impl_rev_name top_pr_bravo \

-partition_name pr_partition \

-source_rev_name top_empty

I don't think that the error come from this file because if the variables like "define_project" or "partition_name" do not correspond to anything in the project I get a clear error message.

I've submitted a support ticket, the person from Altera suggested me to try the PR flow with the last Quartus version 18.1 Pro.

I'll keep you informed if it works or I get a different error message .
