I can't reproduce on windows

[dawbarton]

I can reproduce on Linux. If I get time tomorrow I'll take a look to see what is causing it.

[musm]

Ok thanks for the confirmation, it could be some missing GC.preserve in the sparse code for _copy_sparse_mat

[blegat]

I am also able to reproduce it on Linux:
