Processing Lutan-1 using stripmapApp.py: Segmentation fault

Open ES20180816 opened this issue 1 year ago • 4 comments

Hello,

When using stripmapApp.py to process LuTan-1 data, I encountered a "Segmentation fault" error during the coarse resample stage, leading to the abnormal termination of the rogram.

Do you have any ideas on how to solve this problem?

Many thanks in advance.

Regards.

LuTan-1 support in isce2 is quite new, only recently added by @bjmarfito in https://github.com/isce-framework/isce2/pull/852. Could you post the full output including the segmentation fault message? It would help to know more precisely where in the processing this error occurs.

Thank you, rtburns.
Please find the attached picture, which shows the complete output that led to a segmentation fault, possibly occurring during the refining of secondary timing.

Segmentation fault (core dumped)

By the way, the same error was found when I processed data from other SAR missions (e.g., SAOCOM_SLC).

Any suggestions or comments would be greatly appreciated.

Segmentation fault, very strange. Maybe the platform does not fit.

Did you find the solution. I got similar error while carrying out coregistration
