In addition to not being an infinite loop, it is also not only armel. armhf does not hit the 150 minute timeout, but it also has a factor 10 in the build time with gcc 5 -> 6 for literally the same sources: https://buildd.debian.org/status/logs.php?pkg=rnahybrid&arch=armhf There is no such gcc 5 -> 6 performance regression for rnahybrid visible on the buildds of any other (release or ports) architecture, so this performance regression seems to be specific to 32bit ARM. cu Adrian -- "Is there not promise of rain?"
