This bug is VERY annoying! Although not very reproducible, I can usually hit it after about 4-6 hours of looping ‘fedpkg build’. Considering the whole Coq build is quite lengthy you'd think that one of these commands would hit it much more quickly: $ while true ; do gdb -ex 'set args -coqlib . -q -native-compiler yes theories/FSets/FMapFullAVL.v' -ex run bin/coqc -ex quit ; done or $ while bin/coqc -coqlib . -q -native-compiler yes theories/FSets/FMapFullAVL.v ; do date; done But nope ... My latest thing is to run the gdb command above _and_ run fedpkg build (in another directory) at the same time, in the hope that it's caused by system load.
