Bug ID: 117845
Summary: ICE: Segmentation fault (honor_protect_cleanup_actions
and lower_try_finally during GIMPLE pass: eh )
Product: gcc
Version: 15.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: iamanonymous.cs at gmail dot com
Target Milestone: ---
*******************************************************************************
The compiler produces an internal error during during GIMPLE pass: eh when
compiling the provided code with the specified options.
The issue can also be reproduced on Compiler Explorer.
