** Description changed:
+ [Impact]
+
+ * glm FTBFS using GCC 11, which makes it hard to apply any (security)
+ updates in a timely manner.
+
+ [Test Plan]
+
+ * Check the Launchpad build logs to make sure that glm
+ 0.9.9.8+ds-1ubuntu1 built successfully
+ * Attach build logs to this bug
+
+ [Where problems could occur]
+
+ * The build could still fail for some reason and we would be back to
+ status quo.
+
+ [Other Info]
+
+ * This can be an impish 0-day SRU
+ * PPA pre-testing has been done here:

+ === Original Bug Description ===
+
Unit-tests are failing if built using GCC-11.
```
99% tests passed, 2 tests failed out of 188
Total Test time (real) = 3.86 sec
The following tests FAILED:
- 39 - test-core_func_integer (Child aborted)
- 97 - test-ext_vector_integer (Child aborted)
+ 39 - test-core_func_integer (Child aborted)
+ 97 - test-ext_vector_integer (Child aborted)
```
test-ext_vector_integer seems to be flaky, while test-core_func_integer
fails consistently.
If built with -Wall this warning shows up, which seems to be relevant:
