gdb doesn't work in Linux guest -> fixed in SVN/2.1.4

Reported by: Dummy000001 Assigned to:

Version: VirtualBox 2.1.0 Keywords:
Cc: Guest type: Linux
Host type: Windows

Description

Environment. Host: WinXP/32 SP2 on AMD Athlon64 x2 (old CPU, no fancy VM bits supported). Guest: Debian (Sid) 32 bit.

Starting from VBox 2.1.0, "gdb" under Linux guest can't set breakpoints. That means essentially one can't start program under debugger.

I have strace'd gdb and attaching output.

This is apparently the call where gdb fails:

ptrace(PTRACE_SETREGS, 2390, 0, 0xbfa5aaf8) = -1 EIO (Input/output error)

gdb works fine with 2.0.6.
