Can Segmentation Faults in Linux Be Handled Through Exceptions?

Exception Handling for Segmentation Faults in Linux

In Linux, encountering a segmentation fault typically triggers a SIGSEGV signal. To handle such faults, you can establish a custom signal handler. However, it's advisable to thoroughly debug your code before employing this strategy.

Signal Handling

Normally, upon a segmentation fault, the program receives a SIGSEGV signal. By setting up a handler for this signal, you can minimize the impact of the fault. Ensure that recovery from the situation is feasible.

Exception-Based Approach

Certain libraries, like the one referenced in the answer, convert segmentation fault signals into exceptions. This allows for code that resembles the following:

try
{
    *(int*) 0 = 0;
}
catch (std::exception& e)
{
    std::cerr << &quot;Exception caught : &quot; << e.what() << std::endl;
}

The library utilizes a platform-specific backend to support multiple platforms. It has inherent support for x86 and x86-64 architectures. Backends for other platforms can be obtained from the libjava module within gcc sources.
