Segmentation Fault during database restoration

Hi,

I am new to PostgreSQL. I have been trying to restore a compressed(.gz) database using

gunzip -c filename.gz | psql dbname

After some 8 or 9 tables are restored the program exists giving error: Segmentation Fault.

I have attached the crash report below.
