We found an infinite loop in `nm`. We describe our best effort to understand
the vulnerability below. We attach the relevant files as well. 

*Location* 
https://github.com/bminor/binutils-gdb/blob/binutils-2_36-branch/libiberty/cp-demangle.c#L1548

*Description*
While loop never terminates, as the intermediate conditional statements are not
satisfied. 

*Fix*
Convert while loop to a bounded for loop statement.
