Segmentation fault with long input file (ypp -q)

Post by gfluo » Mon Oct 24, 2011 3:56 am

Dear developers,

Recently, I try to use "ypp -q" to produce the ndb.QP file. Though it works fine for small ypp.in file, it gives "Segmentation fault" (no other single output) when the QPkrange contains over 922 lines. Tests show that the problem does not come from qpdb_setup.F but other initialization programs. I traced back from ypp_i.F, to ypp_init.F, to ypp_init_load.F, and to QP_ctl_load.F, where I lost further clue.

Could you please explain how to solve it? I am using Yambo-3.2.4, rev20 or r941. (The maximum memory use in my system is unlimited to 48GB)

Sincerely,
