function::sprint_stack - Linux

Overview

The function::sprint_stack command is used for debugging purposes in Firefox. It prints the stack trace of the current thread to the console. This can be helpful for identifying the source of an error or crash.

Common Issues

If the function::sprint_stack command does not print any output, it is likely that the debugger.options.stack-frames preference is set to 0. To fix this, set the preference to a non-zero value.

Integration

The function::sprint_stack command can be used with other Firefox debugging tools, such as the debugger command. For example, to print the stack trace of the current thread and then break into the debugger, you can use the following command:

function::sprint_stack | debugger
