The issue stems from a lack of a LINE_MAX definition in Android (see commit 38c957f07038), which is the reason why asprintf() was introduced. We tried adding _GNU_SOURCE definitions to more selftests to fix, but asprintf() may continue to cause problems, and since it is quite late in the 6.9 cycle, we would like to revert 809216233555 first to provide testing for forks[2].
