Corrupted size vs. prev_size

I was trying to unwrap the data! And I am facing this error

corrupted size vs. prev_size
Unexpected or abnormal exit of child process 2928
Abort

It is hard to guess based on the error message only. What data are you using and which steps did you apply so far?

I am trying to produce DEM

C0-registration
Interferogram
Tops deburst
PhaseFieltering
Sbaphu Export
Unwarping

The products are

S1A_IW_SLC__1SSV_20141209T004257_20141209T004324_003635_0044E3_2841
S1A_IW_SLC__1SSV_20141221T004241_20141221T004312_003810_0048DD_EB95

did you select the right bursts for the coregistration? Only a part is covered by both images.

Maybe the interferogram data contains some parts which are covered only in one image and are therefore invalid regarding phase.
