bin/83347: [patch] improper handling of malloc failures within libc's vfprintf

[Dan Lukes]

	Sure ?

	Pointer value of 0 is nothing "magic" for hardware - it's legal to 
write to memory offset 0 unless blocked by explicit configuration. It's 
OS decision to block writes to offset 0. Are you sure it's true for all 
supported platforms ? Yes, I know it's valid for i386/AMD. In advance - 
did you tried in even on platforms that will be supported in the future ?

	In my humble opinion, the one abort() in that special case, even if 
just for sure, has value.

	It's normal that exceptions occur rare. Despite of it, the nice 
programmers shall handle it.

	As you just closed the case I understand your don't want discussion 
about it. No problem - you are commiter - it's your sovereign decision.

	Sincerely
