Hello, I have a project that makes use of some boost components, including regex, format, function, and so on. The things are well with boost of version 1.36. But after I installed boost 1.37.0 and switched the searching paths of the IDE to the ones that relate to the new boost version, I have several ICE's - internal compiler error. The IDE told me the error occured at line 203 of format\feed_args.hpp: oss2 << ' '; I've attemped to prepare a small test program that uses boost::format only to see if boost::format(1.37.0) doesn't support VS2003SP1. But it got compiled well. Anybody has similar experience or any hints of where I should go? Thanks in advance.
