This is a generic problem in gcc.

You should probably file a bug report at

http://gcc.gnu.org/bugzilla/enter_bug.cgi .

You might want to first investigate if this problem is fixed in a later
version of gcc, however.

Or, you could start a discussion at the gcc mailing list

gcc at gcc dot gnu dot org .
