>Description:
An ICE occurs for simple arithmetic on 'unsigned char' in an inlined function.
>How-To-Repeat:
Save this as euk-kr.c.
========================== euc-kr.c ====================================
static inline unsigned int

return 0xfffd;
}

{
unsigned int ch = ksc5601_to_ucs4 (inptr, 0x80);
