Ok, couldn't resist to one more attempt and I may have found the issue. If you look at the n_alloc member in here
https://github.com/joa-quim/GMT.jl/blob/master/src/libgmt_h.jl#L1445 and here http://gmt.soest.hawaii.edu/projects/gmt/repository/entry/branches/5.2.0/src/gmt_resources.h#L543 you'll notice that it is size_t in C an Cint in Julia (converted with Clang). If I change the Julia type to Csize_t than the offsets are the same. Now I'm really going to sleep. sexta-feira, 11 de Setembro de 2015 às 04:07:53 UTC+1, J Luis escreveu: > > No, that's not the case.
