Bug ID: 114250
Summary: [14 regression] ICE when building glslang-1.3.275
(error: invalid types in nop conversion)
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
Assignee: unassigned at gcc dot gnu.org
Reporter: sjames at gcc dot gnu.org
Target Milestone: ---
Created attachment 57621

disassemble.ii.xz
Not sure if this is a dupe of PR114249 but I figured I'd file it for the
testcase if nothing else.
```
