Re: Patch for silent crash with Cygwin1.dll v 1.5.19-4

It really is supposed to be catching NULL dereferences. It's possible of course, that there is something wrong with efault.faulted() but that doesn't mean we need to extra code around efault.faulted. It means that efault.faulted needs to be fixed. i.e., we need to fix the problem not the symptom. cgf I did some more research over the weekend and my problem seems to only come when loading a dll via dlopen() and run_ctors() is called from dll:init() and pthread_key_create() is called during the time that run_ctors() is active. I still have not found who is calling pthread_key_create(), but will be working on this as time permits this week. It's been several years since I did any assembly language coding, so I have to study what's going on when efault.faulted() returns non-zero - and figure out how to get gdb to step through the assembly code.

If you are trying to track down why you get a SIGSEGV in pthread_key_create while running your app in gdb you are wasting your time. This is not a fault, it is expected and normal.
