Segmentation fault(core dump)

[Daniel0xcc]

Getting seg fault while decompiling JSByteCodeWin.bin(acrobat reader 2020).

basically when input this command: ./dead0007 JSByteCodeWin.bin > core.js.

any suggestion?

• I have been audited the code for a while and I would suggest you to check if malloc() returns null ptr to prevent fread() to
  operate on null chunk of memory ;).

Sorry, it's been a long time since I've used this tool, so it's likely very outdated. My guess is that the the 2020 Reader uses a newer file format, not the dead0007 one (or it could also be a different version that still has the same magic bytes). You could try to re-compile this tool with the matching version of Firefox/Spidermonkey (that is used by Reader). In case you manage do that, pull requests are welcome :)
