Hi all, I was notified about some very strange build failure that I cannot reproduce myself, but apparently for Lucas it _is_ reproducible. Have you by chance already come across this problem, or have some idea what could be the problem, or maybe even have a fix already in git?

Is it possible to schedule another build? I'm really clueless what could be going wrong here, other than some problem with the buildd, which seems somewhat more likely given the excerpt of daemon.log provided at the end of this log. Looking at other build logs the above diff seems to be about the last thing before install, and it worked fine on all Debian buildds just a few days ago!?

The fact that it blocks is reproducible. Output on the terminal: % ppl_prolog_generated_test_main.pl compiled 0.18 sec, 2,099,112 bytes % ./swi_prolog_generated_test compiled 0.18 sec, 2,104,128 bytes true. true. % halt if [ . != `pwd` ]; then \ rm -f ppl_prolog_generated_test_common.pl; \ fi rm -f ppl_prolog_generated_test_main.pl; \ diff -u --ignore-all-space ./../tests/expected_pgt obtained_pgt However, it's not diff that is blocking, it's ppl_pl. It's eating all the available memory and causes swapping.
