Segmentation Fault: Core Dumped when running RFFFT

[RCCRAFT1]

Upon accessing a 16 bit INT baseband recording, strf returns with a segmentation fault while running rffft to generate the necessary .bin files needed to create the .dat file for analysis. In this recording the WAV header was skipped, so there is nothing identifying the WAV.

I am not sure why this is happening, as it seems to work completely fine on a file that is way less in size. The file that works is ~200MB and the file im trying to put into the program is ~2GB. Does the size difference matter? Should I add some kind of compression?

Removing the -s flag in the initial command does provide the .bin files as well, however pgplot does not display anything. must the recording be in cs16 to work?

Re-inputting the file as a cs16 (proper file type) also spits back segmentation fault
