Bug ID: 122330
Summary: algol68/compile/error-coercion-2.a68 FAILs with
-D_FORTIFY_SOURCE=3
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Keywords: testsuite-fail
Severity: normal
Priority: P3
Component: algol68
Assignee: algol68 at gcc dot gnu.org
Reporter: sjames at gcc dot gnu.org
Target Milestone: ---
I'm looking at test failures in packaging from wiring up algol68. It looks
pretty good but there's a few failures. I'll look into the others, but here's
one for now.
It requires GCC to be built with -D_FORTIFY_SOURCE=N, I tested with N=3.
```
