strace ls doesn't die for me with plain old cygwin installed a while ago.
Is this only with fresh cygwin?

Well, I installed this only about 2 months ago to do gcc testing -- what a fun ride that was! While waiting for the last three P1 gcc bugs to get solved (so they can release gcc7 and open up gcc8 stage1) I decided to troubleshoot expect ... except that I didn't expect to have to fix this strace thing.... DAMN, I really need to work on being brief and succinct!

So yes, fairly a new install. Also, it's in a qemu/kvm vm, not that that should matter (with virtio sata driver). So maybe I should try to debug where ever that TLS data is supposed to get initialized. Also, this is one of those things that didn't happen much when I was actually debugging strace, but at least it is now. This is on 64-bit Cygwin. I just tried on 32-bit a few times and it's working.

On the bright side, better understanding Cygwin's internals will help me be a better Wine programmer.
