Description Richard Biener 2024-05-02 08:43:29 UTC 
When building tensorflow-lite with GCC 13 (the default compiler), there's a
spurious -Wstringop-overflow diagnostic promoted to an error becuause we
build the package with -Werror.  Adding -Wno-error=stringop-overflow causes
other issues to appear:

Likely fixed in newer upstream versions of tensorflow.

It also fails to build with the upcoming GCC 14 like so:

Comment 2 Dominique Leuenberger 2024-05-14 12:08:15 UTC 
tensorflow-lite is the last gcc12 consumer. Being able to eliminate this dependency would mean we can drop gcc12.
