§323a — R53, TWICE IN ONE HOUR: A FAILED BUILD LEAVES THE PREVIOUS BINARY, AND sha1sum READS GREEN (P31 S67)

make build BINARY=ov_SC02_000 returned rc=2 and sha1sum build/ov_SC02_000/ov_SC02_000 printed the LOCKED hash both times — because the failing object was deleted and the previous link survived. Trusting the output file over the exit code would have certified a resegmentation that does not compile as byte-neutral, and scaled it to 38 subsegs. Read the exit code; then read the errors, and filter warnings out first — gcc-2.7.2's hard errors carry no error: prefix and the one line that killed cc1 sits mid-stream (the tail of the log was pure warnings in both cases).
