The following sections describe known issues in the latest gprofng release. For more information, see https://sourceware.org/binutils/wiki/gprofng#Known_Limitations.
Incorrect Source and Disassembly Percentages
The source and disassembly listings display all percentages as zero.
Internal gprofng Function Displayed in Function View
The collector_root function might be displayed in function view. That's an
internal gprofng function that doesn't consume extra hardware resources.
Inactive gprofng-gui Help Menu Items
Various items aren't clickable in the gprofng-gui help menu. They relate
to features that haven't been implemented in the graphical user interface.
Unable to Profile a Running Process by Using gprofng-gui
The "Profile a Running Process" feature hasn't been implemented in the graphical user interface, so it's not a clickable option.
