This libgcc issue is a little recurrent here in FreeBSD. I remember other email threads talking about it. The summary I remember is that we must go the way Linux does it, I think. It was thoroughly explained in past threads. As GCC was/is omnipresent in Unix like systems most of the other projects have standard ways to use the libgcc. I used to think in new libgcc as a drop in replacement for older ones. I know this is a bit simplistic. I remember Linux usually uses just one libgcc at a time, too. This is the winning answer usually here, too. In fact I remember that new libgcc versions triggers systems recompilations for safety reasons. The use of libgcc in FreeBSD makes the procedure unusually complex many times here. It's a source of many problems. This one is one more to add to the list. This just occurred to me now. Please, keep in mind that the case here is caused by the odd use given to this library here.
