I've been unable to reproduce the build failure above.  I see it was
subsequently given back and built successfully:

https://buildd.debian.org/status/fetch.php?pkg=julia&arch=mips64el&ver=0.4.7-6%2Bb3&stamp=1493482076&raw=0

However, I have been able to reproduce the following:

Simply running, e.g. 'debian/shlibdeps pow', 10 or so times in a row
is enough to get it to segfault.
Unfortunately, it doesn't seem to happen when run in gdb.
I don't know why this program [1], which is used to generate
julia.links, would be failing randomly in this way (it seems to occur
after the final 'printf') and only on this architecture.

Peter, do you have any ideas?

Graham
