Have you reported this? Does it happen with both the LLVM internal assembler/linker (I'm a little rusty, I don't remember if the LLVM linker exists for ELF or is only for Mac OS) and GNU binutils? Can you send (here or privately) the output of "make >error.log 2>&1" with the failure?
I haven't reported the problem. It doesn't happen with the LLVM linker, however llvm-ld cannot generate shared libraries on Linux; it can only produce static libraries. I've attached the error log as you requested.
* Workaround a pthread_exit() bug on Linux that causes the process to become a zombie.
Can you detail this more? I remember seeing something on the list, but I am not sure.
When the main thread calls pthread_exit() in Linux, the process becomes a zombie. My memory is fuzzy, but I seem to remember having problems sending SIGSTOP to the process, and was also unable to attach a debugger to the process. Here is an LKML thread that discusses the problem and references a glibc bug report: http://kerneltrap.org/mailarchive/linux-kernel/2009/2/1/4404553 I checked kernel/exit.c in Linux 2.3.35, and it appears the kernel patch to fix the issue has not been applied.
