step 1 :
In file build/ar/ar.c(build is directory generated by configure) , function
xmalloc line 2088 :
Allocate memory to result
step 2 :
In file build/ar/ar.c(build is directory generated by configure) , function
xmalloc line 2090 :
Select the false branch at this point (result==null is false)
step 3 :
In file build/ar/ar.c(build is directory generated by configure) , function
make_new_symdefs line 1756 :
Function xmalloc executes and stores the return value to strings
step 4 :
In file build/ar/ar.c(build is directory generated by configure) , function
make_new_symdefs line 1760 :
Select the true branch at this point
(read(indesc,strings,strs_size)!=strs_size is true), the allocated memory is
leaked
