Si(Electron-Phonon): Segmentation fault (core dumped)

[Bruce]

Dear everybody:

I used tutorial/si/elph_pw_si.py to learn how to calculate the El-Ph correlation of the Si. All running of the qe tasks were successful, but when the script was running to the third last line (cd elphon ; yambo_ph -F init.in), errors occurred:

errors.txt

.
Then I commented the last three lines and cleaned the files, re-running the script elph_pw_si.py. no error occurred.
I entered directory elphon and input command >yambo_ph -F init.in mannually, the same error information occurred as above. However, if I repeat the command 1 or 2 times, errors disappeared (sometimes not worked)and the following 2 commands (ypp_ph -g; ypp_ph) from the script were OK, database files SAVE/ndb.elph_gkkp* obtained.
Finally, the running of the script tutorial/si/elph_qp_si.py also was OK, and I got the file o-qp-0K.qp.

I don't know whether the error still hid in the calculations (if references outputs exist will be better). Could someone tell me why that error occured and disappeared just by repeating the command? How can I really fix the error ?

QE_version = 6.2.0, Yambo_version=4.2.3

this is a package of my input files.
It's seems big files cannot be uploaded,so database files are not included.
