Now that's even cooler ;) If it would work. With the following map:
libtest {
global:
extern "C++" {
Global::*
};
local:
*;
};
ld segfaults. (And it does not recognize the '::' in Global::) It
segfaults because the yacc rule for parsing the "extern" declaration is
wrong. For both problems is a small diff in the attachment. With that I'm
nearly wishless happy ;) (for ELF at least)
Ciao,
Michael.
