Bug ID: 117724
Summary: [15 regression] ICE when building libgit2 (error:
‘TYPE_CANONICAL’ is not compatible)
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Keywords: ice-checking
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: sjames at gcc dot gnu.org
CC: uecker at gcc dot gnu.org
Target Milestone: ---
Created attachment 59657
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=59657&action=edit
smart_pkt.i.xz
This built OK on the 17th, so it's not quite a dupe of the other TYPE_CANONICAL
issues AFAIK.
```
$ gcc smart_pkt.i -c -g
