[arm-gnu] Application crashes in vsprintf . build with arm-none-linux-gnueabi

[Kalpesh Bafna]

Hi Wesołowski,

Thanks for the reply.

I am able to solve the crash. I just increased the stack size of that thread 
(thread created using ptherad_create) while compiling with -O2 option.

It was working with  -O1 without increasing the stack size.

Regards,
Kalpesh B.

Reporting bugs without event checking what "crash" means? Usually
compiler bug is not the first thing too look at ;)

First check if nothing more obvious happens, for example different
optimization levels use different amount of stack space.
