Bug ID: 206899
Summary: [ld-elf] core dump when linking against
x11/nvidia-driver's libGL.so and another library that
links against libthr.so
Product: Base System
Version: 10.2-RELEASE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Many People
Priority: ---
Component: bin
Assignee: freebsd-bugs@FreeBSD.org
Reporter: d...@freebsd.org

I believe this to be the root cause for bug #205149. I will be committing a
work-around that will fix that bug however the underlying issue still remains.
I'm not sure if this is a bug with ld-elf or x11/nvidia-driver however given
that this is not an issue with Linux I am opting for the former.
I think the best wau to explain the bug is with a (reproducable) demonstration:
> sudo pkg install -y nvidia-driver > /dev/null
> touch libtest.c
> cc -shared -o libtest.so -lthr libtest.c
> echo 'int main(int argc, char **argv) { return 0; }' > test.c
> cc -o test -L/usr/local/lib -L. -ltest -lGL test.c
> env LD_LIBRARY_PATH=. ./test
Segmentation fault (core dumped)
> gdb test test.core
