```
Legend: code, data, rodata, value
Stopped reason: SIGFPE
0x0000000000427aa6 in DumpTrack (mp4file=0xf80d10, tid=0x1) at /root/mp4v2/build/mp4v2/util/mp4trackdump.cpp:54
54 msectime /= timescale;
gdb-peda$ p timescale
$1 = 0x0
gdb-peda$
```
I use gdb debug this program, you can see 'timescale' is 0 when open the malicious files.
It cause the SIGFPE. |
