          Issue ID: 20981
           Summary: Segfault for inlined __simd_sto
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW

          Assignee: nobody puremagic.com
          Reporter: moonlightsentinel disroot.org

The following code segfaults on linux64 when compiled with -O -inline:

import core.simd; // Import need for intrinsics

void main()
{
    void16 a;
    simd_sto!(XMM.STOUPS)(a, a);
}

void16 simd_sto(XMM opcode)(void16 op1, void16 op2)
{
    return cast(void16) __simd_sto(opcode, op1, op2);
}
