ruby 2.6.6p146 (2020-03-31 revision 67876) [x64-mingw32]
Backport:
2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN
[ruby-core:99967]

Description

When I try to recursively list directories, the instructions returns an error "*** stack smashing detected ***" / "[BUG] Illegal instruction".
Error only happens when I try to list a big amount of directories.

Specificity:

  • irb
  • WSL / Start Command Prompt With Ruby (logged as domain administrator)
  • remote drive mapped through "net use Z: \remote_storage"

Log:

2:\>irb
irb(main):001:0> Dir['**/*']                                                                                                                 *** stack smashing detected ***:  terminated

 #1 [ruby-core:99969]

Updated by jeremyevans0 (Jeremy Evans) about 4 years ago

One possible approach to avoiding the stack smash is to limit the recursion allowed during directory globbing. Here's a simple approach that does that: https://github.com/jeremyevans/ruby/commit/29edc847b991bb59185b15c16988bc8004299c16

Unfortunately, this simple approach has some disadvantages:

  • May artificially limit recursion (32 levels may not be enough)
  • Doesn't allow a user to specify a recursion level via a keyword argument
  • May leak memory in failure case

If other committers are in favor of this approach despite the limitations, I can submit a pull request for it.

 #2 [ruby-core:99975]

Updated by kawsay (Clément Coquille) about 4 years ago

Here's a repository with 2 scripts that might help debugging.

  • one to create a lot of directories & sub-directories
  • another to clear newly created directories

https://gitlab.com/kawsay/ruby-bug-17162

Sadly I haven't got a lot of time to consecrate to this, nevertheless I'll keep you updated if I manage to recreate the bug on a test environment

Although I couldn't reproduce this issue even with 68 levels (exceeded the NTFS limit at that time), does this help?
