Bug ID: 107191
Summary: [modules] ICE when importing module partition
(internal compiler error: in tree_node, at
cp/module.cc:9061)
Product: gcc
Version: 11.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: tortoise_74 at yahoo dot co.uk
Target Milestone: ---
Created attachment 53681
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=53681&action=edit
Sample code to reproduce the above
I have been trying to create a module composed of 2 partitions one of which
imports the other.
This gives me the error as below:
```

I thought this might be the same as
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=99769
The line number is different but I am using the ubuntu version of gcc which
might have small differences:
> gcc --version
gcc (Ubuntu 11.2.0-19ubuntu1) 11.2.0
In trying to create a reproducer I have encountered different errors:
