I can file a bug report. But, I'm not entirely sure what to write.
Simpler case:
> julia -p 4
> @everywhere using ZChop (simple modules)
The following version is from a completely fresh build today. I don't get a
crash immediately, but I do get
WARNING: replacing module ZChop (4 times)
Version 0.4.0-dev+6394 (2015-07-29 21:58 UTC)
Commit a2a218b* (0 days old master)
Five days ago, i did git pull and built from an older clone
Version 0.4.0-dev+6202 (2015-07-24 01:47 UTC)
Commit 53a7f2e* (5 days old master)
This version prints the same warning and spews many errors including
unknown function (ip: 0x7fe94d596ff7)
ERROR (unhandled task failure): EOFError: read end of file
The following version will load ZChop with no problem, but when loading
Distributions, it still prints many errors
and fails. It loads some other modules (i.e with @everywhere, as above),
such as Roots with no apparent errors.
Version 0.4.0-dev+3965 (2015-03-22 12:24 UTC)
Commit e1f0310* (129 days old master)
A fresh build today on another machine gives errors with @everywhere using
Roots.
It fails to load Distributions even with no parallel threads, but this
appears to be unrelated.
On the same (other) machine, the following version loads and runs parallel
code using the modules
mentioned above, and more.
Version 0.4.0-dev+4096 (2015-03-31 08:05 UTC)
Commit a3c0743* (120 days old master)
I see no error with 0.3.5-pre+121 (2015-01-07 00:19 UTC)
