From: Göran Weinholt <goran <at> weinholt.se> To: bug-guile <at> gnu.org Subject: future.test randomly hangs in 2.2.4 Date: Mon, 06 Aug 2018 11:59:40 +0200
Hello schemers,
While trying to reproduce #31776 (FAIL: gc.test: gc: after-gc-hook gets
called), I managed to provoke a random hang in future.test. This was
done while /proc was unmounted and these warnings were printed before
the test:
GC Warning: pthread_getattr_np or pthread_attr_getstack failed for main thread
GC Warning: Couldn't read /proc/stat
FWIW, asyncs.test also printed this at one point: ERROR: asyncs.test:
preemption via sigprof - arguments: ((vm-error vm-run "Unrewindable
partial continuation" (#<vm-continuation 559aa17ca710>)))
