https://blogs.gentoo.org/ago/2020/07/04/gentoo-tinderbox/ Issue: dev-python/Frozen-Flask-0.18-r1 fails tests (lto). Discovered on: amd64 (internal ref: lto_tinderbox) NOTE: This machine uses lto with CFLAGS=-flto -Werror=odr -Werror=lto-type-mismatch -Werror=strict-aliasing Here is a bit of explanation: -Werror=lto-type-mismatch: User to find possible runtime issues in packages. It likely means the package is unsafe to build & use with LTO. For projects using the same identifier but with different types across different files, they must be fixed to be consistent across the codebase. -Werror=odr: Used to find possible runtime issues in packages. These bugs are a problem anyway but may be even worse when combined with LTO. C++ code must comply with the One Definition Rule (ODR) - see https://en.cppreference.com/w/cpp/language/definition#One_Definition_Rule. -Werror=strict-aliasing: Used to find possible runtime issues in packages. These bugs are a problem anyway but may be even worse when combined with LTO. Workarounds: - If upstream is friendly and still active, file a bug upstream. For emulators, codecs, games, or multimedia packages, it may be worth just applying a workaround instead, as upstreams sometimes aren't receptive to these bugs (VALID FOR ALL). - Use the new 'filter-lto' from flag-o-matic.eclass as it's likely to be unsafe with LTO (VALID FOR lto-type-mismatch - odr). - Fix it yourself if interested, of course (VALID FOR ALL). - Append-flags -fno-strict-aliasing (VALID FOR strict-aliasing). - Use memcpy() but a union is sometimes suitable too (VALID FOR strict-aliasing). - -fstrict-aliasing is implied by -O2, so this must be addressed in some form (VALID FOR strict-aliasing).

Error(s) that match a know pattern: AssertionError: Popped wrong app context. (<flask.ctx.AppContext object at 0x00007fe34e2f6138> instead of <flask.ctx.AppContext object at 0x00007fe34cbf4170>) FAILED (errors=1) RuntimeError: Working outside of request context.
Logs clearly indicate the problem has nothing to do with LTO. Indeed, the package does not compile any code to begin with. ====================================================================== ERROR: test_ignore_pattern (flask_frozen.tests.TestWithoutUrlForLog) ---------------------------------------------------------------------- Traceback (most recent call last): File "/usr/lib/pypy3.9/site-packages/flask/ctx.py", line 399, in pop self.app.do_teardown_request(exc) File "/usr/lib/pypy3.9/site-packages/flask/app.py", line 2370, in do_teardown_request for name in chain(request.blueprints, (None,)): File "/usr/lib/pypy3.9/site-packages/werkzeug/local.py", line 316, in __get__ obj = instance._get_current_object() # type: ignore[misc] File "/usr/lib/pypy3.9/site-packages/werkzeug/local.py", line 513, in _get_current_object raise RuntimeError(unbound_message) from None RuntimeError: Working outside of request context.
