I checked with Valgrind and you were right about lapack and It's related to my openblas (built which 64 bit interface)

I have something like this when check for restriction on lfp (lfp=0) in my example

==26438== Process terminating with default action of signal 11 (SIGSEGV)
==26438==  Bad permissions for mapped region at address 0x9EBD000
==26438==    at 0x55E1CC4: idamax_k (in /usr/lib/libopenblas_sandybridgep-r0.2.6.so)
==26438==    by 0x5B275A6: dgetf2_ (in /usr/lib/liblapack.so)
==26438==    by 0x5B27D00: dgetrf_ (in /usr/lib/liblapack.so)
==26438==    by 0x4F24468: gretl_invert_general_matrix (gretl_matrix.c:7111)
==26438==    by 0x4F442ED: check_R_matrix (gretl_restrict.c:100)
==26438==    by 0x4F4645B: test_restriction_set (gretl_restrict.c:2285)
==26438==    by 0x4F47FBA: gretl_restriction_finalize_full (gretl_restrict.c:2469)
==26438==    by 0x4F5BA68: gretl_cmd_exec (interact.c:4847)
==26438==    by 0x40442C: exec_line (gretlcli.c:1113)
==26438==    by 0x403295: main (gretlcli.c:611)

When I do the same example as above is just complained that the matrix is singular.

I have the version 3.4.2.1 of lapack
I don't if it is related but I also use openblas as blas.

Uhm, that's strange. The script you sent runs fine here. What are your configure options? Also, could you try running the script that provokes the segfault under valgrind and see what happens?

Wild guess: something strange may be happening when doing QR decomposition. What version of lapack are you using?
