Hi, a bug in my own code - a forgotten binary type, I should learn better Tcl. It FAILs only for specific deterministically-random build-id hashes, this one 4edd6ca0c5be6b98d27ae5f0b31bbfe782ebd2aa was read incorrectly as 4edd6ca07e6b98d27ae5f0b31bbfe782ebaa resulting in FAIL: build-id: breakpoint function, optimized file FAIL: build-id: breakpoint small function, optimized file FAIL: build-id: run until function breakpoint, optimized file FAIL: build-id: run until function breakpoint, optimized file FAIL: build-id: run until breakpoint set at small function, optimized file Approval requested although the fix is obvious. Sorry, Jan
