Re: how to set some value at a memory location in stack
I am posting the config.log file generated.
It says segmentation fault and cc1: error: unrecognized command line
option "-std1" at a couple of places.
Please have a look at it. I am trying to track down the problem myself
but I am doubtful to succeed without an expert's help.
Thank You
