--- Comment #12 from Martin Lederhilger <m...@convergent-it.at> 2011-08-18 12:27:50 UTC --- For the case with using "extern template...": If you look at bug #40068, you can see that there was a similar problem (not exported typeinfo to DLL) once - for normal classes. There were two solutions, one in comment 1 (has not been applied to GCC) and another in comment 4 (has been applied to GCC). If I apply the patch of comment 1, then my problems with the not exported typeinfo disappears;) It would be nice, if someone with more knowledge than me can have a look at this (and how it could be applied to GCC). Thanks
