Summary: compiler crashes

Initial Comment:
I compile using
sdcc -mpic14 -p16c745 -c --std-c99 USB.c
My sdcc version is
SDCC :
mcs51/gbz80/z80/avr/ds390/pic16/pic14/TININative/xa51/ds400/hc08
2.5.6 #1246 (Apr 12 2006) (UNIX)

Trying to compile the code below (from the attached
file) results in a segmentation fault.

#include <pic16c745.h>
#include <stdint.h>

struct usb_buffer
{
	uint8_t bmRequestType;

	uint8_t bRequest;

	uint16_t wValue;

	uint16_t wIndex;

	uint16_t wLength;
};

void usb_token_setup(void)
{
	static struct usb_buffer buffer; // Nonstatic doesn't
work in sdcc 2.5.6
	void *b = (__data uint8_t *)(BD0OAL + 0x100);

	//memcpy(&buffer, b, sizeof(buffer)); won't work in
sdcc 2.5.6
	{
		uint8_t i;
		const uint8_t *bp = b;
		uint8_t *bufferp = &buffer;
		for(i = 0; i < sizeof(buffer); i++)
			bufferp[i] = bp[i];
	}
}
