> Solaris C++ compiler use a lot of space on stack in fastdebug build to allocate on stack char (from FormatBuffer used by err_msg()) for each assert. As result VM crashs with stack overflow in C2 compiler threads in recursive methods. It is triggered by changes in the recent 292 push which added err_msg() call in asserts in node.hpp file.
> Added new FormatBufferResource class to use thread's resource area for error message buffer. Added new err_msg_res() to use new class and use it in C2 instead of err_msg(). Removed workaround from makefile for C2 files.
