TextSearch finished searching for sys_beos in vlc sources and I left it open. I then ran make and it crashed. Reproduced it several times.

TextSearch keeps monitoring all files and folders that it scanned, to adopt for changed search results. To analyze this bug, I would build TextSearch with DEBUG=1. This can also be added selectively when building a Haiku image, see build/jam/UserBuildConfig.Readme/Sample. When it crashes, in the Debugger it is then hopefully obvious why.

The second segment violation disassembly seems weird:

  • the dump shows use of 0x8(%ebp), 0xc(%ebp) and 0x10(%ebp), which, for a non static function, makes two pointers parameters.
  • _NodePath() definitely has only one pointer parameter.

Am I missing something?

Replying to korli:

  • the dump shows use of 0x8(%ebp), 0xc(%ebp) and 0x10(%ebp), which, for a non static function, makes two pointers parameters.
  • _NodePath() definitely has only one pointer parameter.

Am I missing something?

The return type is BString. One of those pointers (don't know off the top of my head whether it's the first or the last) points to the return object.
