Hi!
I am having a strange problem with a segfault that seemingly appeared out of nowhere while calling Fortran code on OSX. When I try to run the tests of my Dopri.jl <https://github.com/helgee/Dopri.jl> package on Julia 0.4.5 on OSX 10.11.5 the process consistently fails with this error message: signal (11): Segmentation fault: 11 unknown function (ip: 0x0) Tests pass on master and 0.3.12. Could somebody try to reproduce this behavior on their machine? What puzzles me is that this did not happen 23 days ago when I fixed the lastest issue with the package. In the meantime I did not change anything about neither the code nor the Julia runtime. I did install an OS update, though. Any ideas? The only other data point I have is that the tests also segfault on 0.3 on Travis but not consistently. On the third to fourth re-run the build usually succeeds. I have attached the log. Cheers, Helge
