  2. Stack trace - Wikipedia

    en.wikipedia.org/wiki/Stack_trace

    In computing, a stack trace (also called stack backtrace [1] or stack traceback [2]) is a report of the active stack frames at a certain point in time during the execution of a program. When a program is run, memory is often dynamically allocated in two places: the stack and the heap. Memory is continuously allocated on a stack but not on a ...

  3. Exception handling (programming) - Wikipedia

    en.wikipedia.org/wiki/Exception_handling...

    Explicit use of empty exception specifications could, however, allow C++ compilers to perform significant code and stack layout optimizations that are precluded when exception handling may take place in a function. [23] Some analysts viewed the proper use of exception specifications in C++ as difficult to achieve. [47]

  4. Exception handling syntax - Wikipedia

    en.wikipedia.org/wiki/Exception_handling_syntax

    Exception:: Class is a base class and class-maker for derived exception classes. It provides a full structured stack trace in $@ -> trace and $@ -> trace -> as_string . Fatal overloads previously defined functions that return true/false e.g., open , close , read , write , etc.

  5. Segmentation fault - Wikipedia

    en.wikipedia.org/wiki/Segmentation_fault

    Here is an example of ANSI C code that will generally cause a segmentation fault on platforms with memory protection. It attempts to modify a string literal, which is undefined behavior according to the ANSI C standard. Most compilers will not catch this at compile time, and instead compile this to executable code that will crash:

  6. Resource acquisition is initialization - Wikipedia

    en.wikipedia.org/wiki/Resource_acquisition_is...

    Exception safety is provided for stack resources (resources that are released in the same scope as they are acquired) by tying the resource to the lifetime of a stack variable (a local variable declared in a given scope): if an exception is thrown, and proper exception handling is in place, the only code that will be executed when exiting the ...

  7. Comparison of Java and C++ - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_Java_and_C++

    Compiled Java code files are generally smaller than code files in C++ as Java bytecode is usually more compact than native machine code and Java programs are never statically linked. C++ compiling features an added textual preprocessing phase, while Java does not. Thus some users add a preprocessing phase to their build process for better ...

  8. Stack buffer overflow - Wikipedia

    en.wikipedia.org/wiki/Stack_buffer_overflow

    Stack canaries, named for their analogy to a canary in a coal mine, are used to detect a stack buffer overflow before execution of malicious code can occur. This method works by placing a small integer, the value of which is randomly chosen at program start, in memory just before the stack return pointer.

  9. List of Java bytecode instructions - Wikipedia

    en.wikipedia.org/wiki/List_of_Java_bytecode...

    push a constant #index from a constant pool (String, int, float, Class, java.lang.invoke.MethodType, java.lang.invoke.MethodHandle, or a dynamically-computed constant) onto the stack (wide index is constructed as indexbyte1 << 8 | indexbyte2) ldc2_w 14 0001 0100 2: indexbyte1, indexbyte2 → value
