The problem is in this part of the frame:
.LASFDE3:
.long .LASFDE3-.Lframe1
.long .LHOTB2
.long .LHOTE2-.LHOTB2
.long .LCOLDB2
>>> .long .LCOLDE2-.LCOLDB2
.uleb128 0x0
.byte 0x4
.long .LCFI2-.LFB3
.byte 0xe
.uleb128 0x10
.byte 0x86
.uleb128 0x2
.byte 0x4
.long .LCFI3-.LCFI2
.byte 0xd
.uleb128 0x6
.align 8
.LEFDE3:
If the marked line is changed to .long .LCOLDB2-.LCOLDB2 (or ..E2 - ..E2) the
compilation succeeds. However, looking through asm, it looks correct to me.
