The monolithic build includes ICU and that uses dynamic_cast in numerous places. That said, I doubt that's the reason for the crash. Search the group for recently reported crashes. In most cases it's a matter of ensuring both V8 and your own code are compiled with -DV8_COMPRESS_POINTERS. -- -- v8-users mailing list v8-users@googlegroups.com http://groups.google.com/group/v8-users --- You received this message because you are subscribed to the Google Groups "v8-users" group.
