UNEXPECTED_KERNEL_MODE_TRAP BSODs when trying to index files with Everything #515

Open aziztcf opened 2 years ago

aziztcf commented 2 years ago

This has happened before with other software too but with Everything I can reproduce it consistently.

  1. add BTRFS drive to search folder
  2. select it and rescan now
  3. BSOD

attached are two minidumps, I did take a peek with windbg but sadly my windows dev skills aren't too great! minidumps.zip

Apparently recursion shenanigans. Maybe something to do with // FIXME - recursion is a bad idea in kernel mode ;)

Thanks, I'll try to reproduce. I think you're probably right given the comment, it's probably running out of stack space.
