When you say that the linker "add the template class as thumb" I assume 
that you mean that the linker creates a calling stub between your arm32 
application and the instance of the class, and that this stub switches 
over to thumb mode before executing the class ?

It sounds as if G++ is failing to label the class code as being arm32 
code.  If you look at the compiler's assembler output for the class what 
do you see ?  Is there a ".code 32" pseudo op ?

Anyway it is most likely that this is a compiler bug rather than a 
binutils bug.  Can you put together a *small* piece of test code which 
demonstrates the problem and submit it to the gcc bugs mailing list ?

Cheers
