OpenOCD crashes when I want to program one of five CPLDs in a JTAG chain. When I have four or less, it just works.

I have 5 XC9572XL devices on my board in a chain. And I'm using the GPIO on a Xilinx Zynq through sysfs gpio from linux. I let Xilinx iMPACT generate an SVF file for programming a single device. OpenOCD does detect all 5 devices but when it comes to programming it crashes with some error about free() finding an invalid next size.

When I use an original Xilinx Platform Cable USB II I can program all devices without a problem.
