Summary: Crash removing last visible extension from Extension
Manager
Severity: normal
Classification: Unclassified
OS: All
Reporter: [email protected]
Hardware: Other
Status: NEW
Version: 4.1.0.0.alpha0+ Master
Component: Libreoffice
Product: LibreOffice
In "Tools - Extension Manager..." deselect "Type of Extension" "Installation"
and "Shared", leaving only "User" selected. With just one such extension
installed, select it and chose "Remove".
At least with certain --enable-dbgutil builds that can lead to stderr output
> /usr/lib/gcc/x86_64-redhat-linux/4.7.2/../../../../include/c++/4.7.2/debug/vector:336:
> error: attempt to subscript container with out-of-bounds index -1, but
> container only holds 0 elements.
> Objects involved in the operation:
> sequence "this" @ 0x0x2a36100 {
> type =
> NSt7__debug6vectorIN5boost10shared_ptrIN6dp_gui10Entry_ImplEEESaIS5_EEE;
> }
and a SIGABRT crash. The reason is that m_bHasActive and m_nActive members of
ExtensionBox_Impl (desktop/source/deployment/gui/dp_gui_extlistbox.hxx) are not
properly synchronized, so that it can happen that while one thread is somewhere
past
