Doc Type: Bug Fix
Doc Text:
Previously, there was a missing sign extension in the x86_64 ptrace code that may have caused gdb to fail on the x86_64 architecture when debugging an i386 application. With this update, the missing sign extension is now correctly extended, which resolves this issue.

There is a missing sign extension in x86_64 compatibility ptrace code and x86_64 gdb sometimes fails when debugging i386 application because of it.
