Glad to turn on the flashlight so that you may see the hole. I hope
you know which way to dig now. :-)
I can't figure

No, the pain would be a dangling pointer.
Thanks for the response.

I can't figure out why every GTY()-ed global data (extern or static) should

Couple of big limiations of GCC PCH :
