yes, i know this problem occur when specified RTLD_GLOBAL.
but in Solaris's manual, they recommends it:

Sun Studio 12: C++ User's Guide
16.8 Using dlopen to Access a C++ Library From a C Program
http://docs.sun.com/app/docs/doc/819-5267/bkamv?l=Ja&a=view

"When shared libraries are opened with dlopen(), RTLD_GLOBAL must be
used for exceptions to work."


and again, this problem is NetBSD specific problem. neither
{Free,Open}BSD nor Linux.
they already solved this problem by using --eh-frame-hdr.

very truly yours.
