[Bug] - Decompiled code not returned for function

[re-fox]

An issue exists where there is inconsistent data being returned from rz-retdec (built from latest master). When running retdec independently, the function will decompile properly, however under rizin the function shows no decompiled code.

# rizin -v
rizin 0.5.0 @ linux-x86-64
commit: 9a7567962632fbc2ec612486283df10ca6dad217

When running retdec independently against this sample helloworld.zip , the function function_401030 will return the following decompiled function

// Address range: 0x401030 - 0x401082
int32_t function_401030(uint32_t a1) {
    // 0x401030
    if (a1 <= 0) {
        // 0x401074
        return 0;
    }
    int32_t v1 = 0; // 0x40104f
    int32_t result = 0; // 0x40106c
    int32_t v2; // 0x401030
    int32_t v3 = &v2; // 0x401030
    result += *(int32_t *)v3;
    v1++;
    v3 += 4;
    while (v1 != a1) {
        // 0x40105d
        result += *(int32_t *)v3;
        v1++;
        v3 += 4;
    }
    // 0x401074
    return result;
}

When opening the binary with rizin+rz-retdec, the function returns no decompiled code.
