This is a known bug in gcc, but it's very obscure and it seems unlikely to be solved soon. Therefore you might consider to apply the patch below as a workaround.

Since I don't know how fix it in gcc and nobody else seems to be working on that, I suggest you apply the following workaround: ----------------------------------------------------------------------
