forget the one-in-three: these show up in dbg and rel full mode, since r697 ( issue #732 ) but no clear connection with that. can't repro on my own win7 machines.

The first error:

Dr.M
Dr.M Error #1: UNINITIALIZED READ: reading register eax
Dr.M # 0 USER32.dll!GetClipboardData +0x2a (0x76c69f47 <USER32.dll+0x59f47>)

Dr.M Note: @0:00:12.427 in thread 3728
Dr.M Note: instruction: cmp 0x08(%ebp) %eax

According to the code: the eax was from [ebp-0x2c], which should be initialized in 0x76c87cd7,
which performs a system call with syscall number: 0x10f9.

USER32!GetClipboardData:
