Fixed the problem.
I built library in glibc and the sample application using newlib. Now, I changed both to glibc and partially fixed some problem.

I used the tool gllvm to build the whole-program LLVM bitcodes file (tiffsplit.bc). Then I used afl-clang-fast compile it to generate the instrumented binary. However, it gives an error. I found a similar problem on github. I am searching for a long time on net. But no use. Please help or try to give some ideas how to achieve this.
My commands are as follows:
CC=gclang ./configure --enable-shared=no --enable-static=yes
make -j$(nproc)
get-bc tiffsplit
afl-clang-fast tiffsplit.bc -o tiffsplit
The error is as follwos:

I'm getting the error undefined local variable or method '_1' for main:Object when I run the following code. Any idea why I'm getting this error? and how can I store the result in a variable.
result="-e hostname=webserver001 -e username=root -e password=testing123"
p result.scan(/\w+=\w+/)
.map { _1.split("=") }
.to_h

You're probably running an older version of ruby - the numbered parameters for blocks have been available in ruby since 2.7 - see https://www.bigbinary.com/blog/ruby-2-7-introduces-numbered-parameters-as-default-block-parameters
You can make it work on older version by using
p result.scan(/\w+=\w+/)
.map { |s| s.split("=") }
.to_h
I'm getting the error below
$ bundle exec rspec calculatorcli_spec.rb
Failure/Error: c = CalculatorCLI.parse
NoMethodError:

CalculatorCLI is a class, and you're missing its initialization
either change CalculatorCLI.parse to CalculatorCLI.new.parseor changedef parsetodef self.parseinCalculatorCLI` definition
If I run:
myObj.methods - Object.methods
I see the method I expect listed in the results:
[:myMethod]
If I then run:
myObj.myMethod()
I get the following error:
symbol lookup error ... undefined symbol: myMethod
What is happening? Am I calling myMethod correctly?
Sometimes I see code using to_d. The ruby documentation even states there is a Float#to_d method. However, it's not in my version of ruby (ruby 1.9.3p263 (2012-08-23 revision 36792).
1.9.3p263 :001 > "0.0".to_d
NoMethodError: undefined method `to_d' for "0.0":String

No to_d in Float, String or Fixnum. What's going on?
As stated in the example of the documentation you need
require 'bigdecimal'
require 'bigdecimal/util'
