How to avoid the "memory ... exhausted" error when using debug_backtrace () in a custom error handler?

Question

I wrote an error handler for my website that looks like this:

function errorHandler($number, $string, $file, $line, $context, $type = '') {
// save stuff in DB
}

What I am registering like this:

set_error_handler('errorHandler', E_ALL);

I save all the passed variables to the DB as well as the return line to help me debug the problem:

print_r(debug_backtrace(DEBUG_BACKTRACE_PROVIDE_OBJECT), true)

The problem is that I sometimes get this error:

The allowed memory size of 134217728 bytes has been exhausted (tried to allocate 30084081 bytes)
