[Libreoffice] bug in GCC 4.6.1?

Hullo List,

I recall mention on the list that the LO build was finding bugs in 
various build programs, but I was only paying peripheral attention.  Now 
I've run across something from GCC 4.6.1 that says:

lto1: internal compiler error: in lto_symtab_register_decl, at 
lto-symtab.c:148
Please submit a full bug report,
with preprocessed source if appropriate.

when attempting to create libfrmlo.so

$ g++ -shared [...] -o $W/LinkTarget/Library/libfrmlo.so

Is this something "we've" already encountered, reported, or otherwise 
dealt with?  Or is this another "just me" case.

Thanks,

Kevin
