rustc 'deadlock detected'
I've reported this in the past as intermittent and for a long time it
had completely disappeared so I wasn't really able to debug it.
However I've now got into a state where I'm seeing this pretty much 100%
of the time both in a standalone build chroot and in my auto builds.
Build system is:
NetBSD trigati.mudcovered.org.uk 9.0_BETA NetBSD 9.0_BETA (GENERIC) #0:
Fri Oct 18 20:30:55 BST 2019
Failure I'm seeing (Although not always in exactly the same place)
Compiling proc-macro2 v0.4.30
Compiling unicode-xid v0.1.0
Compiling syn v0.15.35
Compiling ryu v1.0.0
Compiling serde v1.0.92
Compiling libc v0.2.60
Compiling fixedbitset v0.1.9
Compiling ordermap v0.3.5
dead lock detected
error: Could not compile `proc-macro2`.
warning: build failed, waiting for other jobs to finish...
It was pointed out last time I raised this that the message comes from
rtld.c (Where it appears twice). I don't get any core dumps that I can
debug to work out what is going wrong. Is there anything I can do to
help track this down?
