cat > bug.d << CODE import core.simd; void foo(int4 a, ubyte16 b) { } CODE dmd -c -g bug.d ---- dwarfdump bug.o ---- dwarfdump: A parent DW_AT_sibling of 0x0000007a points at the first child 0x0000007a so the die tree is corrupt (showing section, not CU, offsets). The subrange for the vector is encoded incorrectly.

GDB currently seems to crashe while reading that debug info.
