Segmentation fault

Description

Hello,

I am trying to continue running a job (xleos) that has run successfully before. I only changed the start dump but I now get a segmentation fault.

xleos000.xleos.d15176.t112733.leave:

Application 15458221 is crashing. ATP analysis proceeding...

ATP Stack walkback for Rank 0 starting:
  [empty]@0x0
ATP Stack walkback for Rank 0 done
Process died with signal 11: 'Segmentation fault'
Forcing core dumps of ranks 0, 1
View application merged backtrace tree with: stat-view atpMergedBT.dot
You may need to: module load stat

I am manually compiling using the following handedit:
~ukca/hand_edits/VN8.4/manual_comp_ARCHER.ed

Best wishes,
Ines

Without a comp.leave file, its hard to follow what you have done. Please do a full rebuild and keep the leave file output.

I notice that you are using a defunct version of netcdf. You need to change this so that the default is loaded ie

module load cray-netcdf

and not as you have "module load cray-netcdf/4.3.1"

Dear Grenville,

I have saved the output from the manual compilation to

/home/n02/n02/ih280/output/xleos-181083832.comp.leave

There were other messages on the screen which I have copied to

/home/n02/n02/ih280/output/xleos-181083832.screen

This is the corresponding .leave file:

/home/n02/n02/ih280/output/xleos000.xleos.d15181.t083844.leave

I am not sure how I have loaded "module load cray-netcdf/4.3.1". I have put "module load cray-netcdf" into my .profile?

Best,
Ines

Hello,

I have taken a copy from the job and started from the same start dump from which xleos ran successfully before. This new job is xleow.
I get the same segmentation fault as for xleos.

Best,
Ines

Please try a complete rebuild but switch off the use of prebuilds.
