Description Agostino Sarubbo gentoo-dev 2022-06-24 08:23:19 UTC

Issue: app-accessibility/edbrowse- does not respect CFLAGS.
Discovered on: amd64 (internal ref: tinderbox)

This machine uses lto with CFLAGS=-flto -Werror=odr -Werror=lto-type-mismatch -Werror=strict-aliasing
To reproduce this issue you may want to add "-frecord-gcc-switches" to CFLAGS/CXXFLAGS/FFLAGS/FCFLAGS. If this is not something about c/c++ context see this bug as an hint to hide the QA warning (with QA_FLAGS_IGNORED) where is not possible to respect CFLAGS.
