Bug ID: 94896
Summary: [10 regression] ICE: canonical types differ for
identical types
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
Target Milestone: ---
Target: sparc-sun-solaris2.11
Between 20200429 (27594524d8a93cddb197ad8c9d4075c5870f1473) and 20200430
(c416c52bcdb120db5e8c53a51bd78c4360daf79b), two tests regressed on
Solaris/SPARC:
