The problem is that our crt foo is incompatable with g++'s constructor and thread mechanism. In order to get g++ working at yahoo, we had to back out to the old crt{i,n}.o and use gcc's crt{begin,end}.o so that the frame hooks etc were called in the right places. See glibc's own crtbegin/end etc for how to do an elf-specific set of crt files that remain gcc/g++ compatable. According to my recollection of the original AT&T/USL manuals that I have (in Australia) that cover ELF, toolchain, linking, abi's, etc, I still believe our crt{i,n}.o are broken. We have replaced the extensible "linker set"-like mechanism that was part of the ELF linking defintion with a static _init() and _fini() function. Other systems, notably g++, depend on the original system working. Anyway, I will be checking out the details in about 2 weeks when I get back to .au and look it up. -Peter To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
