Hi,
I recently performed an (unofficial) archive rebuild with GCC 8 on
mips64el. The main purpose of the rebuild was to discover mips toolchain
regressions, however I noticed this error in the logs which might be
interesting to you:

Probably the for loop condition should be:
af < aftry + sizeof(aftry)/sizeof(*aftry)
