# Install a snapshot of GCC that we want to test with.
# GCC 15 will break our code: https://github.com/Mbed-TLS/mbedtls/issues/9814
# During a transition period, we will use a snapshot of GCC 15 to test the
# fix for that issue.
# Eventually, gcc-latest should become GCC 15. This will cause test failures
# on branches that don't have the fix yet, which is why we don't make
# GCC 15 be gcc-latest immediately.
