Hello,
mc is one application that uses the S-Lang library. While running mc on
Ubuntu 22.04, we observed one FPE bug as follows:
Program received signal SIGFPE, Arithmetic exception.
0x00007ffde904e6fe in tt_sprintf (buf=0x7fffffffdab0
"{1000}/\203\065\065.2X/0.2X\033\\", buflen=1024, fmt=0x5555556ba925
"%2.2X\033\\", x=0, y=0) at ./src/sldisply.c:644
644 ./src/sldisply.c: No such file or directory.
