Bug ID: 123407
Summary: nternal compiler error: Segmentation fault with
redeclared symbols
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: d
Assignee: ibuclaw at gdcproject dot org
Reporter: ibuclaw at gcc dot gnu.org
Target Milestone: ---
Merging global symbols with the same mangle name doesn't take into account it
might be a redeclaration of a different kind of symbol.
```
pragma(mangle, "ice") int fun();
pragma(mangle, "ice") int var;
```
ice.d:2:27: internal compiler error: Segmentation fault
