Symbolic factorization segfault (for MaPHyS integration)
When using MaPHyS + Pastix 6 on the matrix young1c with 8 processes, we obtain a segmentation fault during symbolic factorization.

*** Error in `./zmph_paddle': realloc(): invalid next size: 0x00000000026222f0 ***
======= Backtrace: =========
After investigation, it seems that matrices 3 and 6 are concerned by the segmentation fault.
- the 8 subdomain matrices. matrices.tar
- the 8 domains description. The schurlist corresponds to the "myindexintrf" in the file. domains.tar
- The 8 "ordergen" and "symbgen" files dumped with IPARM_IO_STRATEGY = PastixIOSave. newpastix_ordergen.tar
- The same 8 "ordergen" and "symbgen" files but with the old pastix. oldpastix_ordergen.tar
