uniprocessor
>Description:
The attached program has a error. The function strtok should not be executed on a const string. Thus a segmentation fault occurs.
but in gdb when running the program in step mode, segmentation fault does not occur. Again, if the same program is run in gdb without breakpoints, segmentation fault occurs.
>How-To-Repeat:
compile with cc -g -o a a.c
run "gdb a"
execute in step mode
break 4
step
step etc...
no segmentation fault occurs even though it should
next remove breakpoints and give run command in gdb
now segmentation fault occurs
