Fortran Runtime Error in ft8d.f90 #1092

Description of the setup:

Description of the problem:

I've been running an FT8 skimmer for several months. Recently, it started failing to function with the error below. I thought I might have corrupted the filesystem, so I reformatted the SD card, downloaded the latest image, and set up the system again from scratch. However, it is still failing with the same error.

Excerpt from decode-ft8.log:

Sun Apr 23 21:43:01 UTC 2023

Fortran runtime error: Cannot open file 'ft8_*_230423_2143.c2': No such file or directory

Error termination. Backtrace:

Steps to reproduce the problem:

On my system, they are

  1. Configure sdr_transceiver_ft8 to skim 40M-6M
  2. Start it
  3. Observe that in /dev/shm the decodes_*.txt files are empty and decode-ft8.log shows the error above repeating.

The Terminated message indicates that the write-c2-files program was killed before it could write the output files and exit normally. So it seems that the write-c2-files program is hanging for some reason.

If it worked before and does not work now, then it looks like a hardware problem.

Maybe you could check if other applications like LED blinker or SDR transceiver are still working.
