[jira] Resolved: (HARMONY-3287) [drlvm][winx64] Eclipse fails in -Xint with SWTError: No more handles

Gregory Shimansky resolved HARMONY-3287.
----------------------------------------

    Resolution: Fixed

The failure of GdiplusStartup happened to because this function was called from a native method with RSP not aligned to 16 bytes. It is not well documented in MSDN, but it looks like RSP has to be always aligned to 16 bytes. Some functions don't require it, but some do. A patch was made to the interpreter to fix this in assembly code, so if a native method has an odd number of arguments, additional 8 bytes are skilled by RSP to align it to 16 bytes.

Patch applied at 514264.
