#488 Buffer overflow error message from filterbank file

[Araujo Furlan Susana]

Hello, I am trying to use dspsr to get the phase information from a filterbank file. My filterbank file has a size of 2.6 Gb. I am using a .par file to get the ephemeris and be able to get the phase. The version of dspsr that I got from -i was:
dspsr 2 <fftw3></fftw3>

The command that I used was:
dspsr -b 256 -s -O firstrty_phase -nsub 64 -E parfile.par filterbank.fil

I got a buffer memory overflow error message. I tried using the option -T 1, but I got the same error message either way. How can I solve this issue and be able to

dspsr: Loading ephemeris from parfile.par
*** buffer overflow detected ***: dspsr terminated

[Willem van Straten]

Hi, thanks for the bug report. Could you please run dspsr with the -V command line option, and attach the (very) verbose output to this ticket?

[Willem van Straten]

... and if there's nothing top secret in parfile.par, could you please attach it too?
