Do you know what was the previous revision which you used? Also, how was Emacs unresponsive -- did it consume any CPU cycles at all? Were all the threads locked up, or just some? If you detach from it, then attach again, do you see exactly the same backtrace? > #3 0x0114875d in w32_msg_pump (msg_buf=0x5b5aff54) at w32fns.c:2386 > msg = { > hwnd = 0x3f9500bc, > message = 0xf, > wParam = 0x0, > lParam = 0x0, > time = 0x6cc97f02, > pt = { > x = 0xdd, > y = 0x2f > } > } > result = 0x0 > focus_window = 0x403 This looks like the input thread is waiting for GetMessageW to return, which is normal -- it means there's no input, and we are waiting for it. > Thread 1 (Thread 8744.0xf50): > #0 0x7c90e514 in ntdll!LdrAccessResource () from C:\WINDOWS\system32\ntdll.dll > No symbol table info available. > #1 0x7c90d2aa in ntdll!ZwDuplicateObject () from C:\WINDOWS\system32\ntdll.dll > No symbol table info available. > #2 0x7c80df03 in KERNEL32!DuplicateHandle () from > C:\WINDOWS\system32\kernel32.dll > No symbol table info available. > #3 0xffffffff in ??

This is the main thread, but its backtrace looks like the stack is smashed, and real_itimer is a variable, not a function. We need more data points on this.
