Dereference of end() iterator in section category options list
(profiler/src/profiler/TracyView_Options.cpp:152-153)
The new category list iterates categories = m_worker.GetSectionDescriptions()
(the description map) and then looks up each category in sections = m_worker.
GetSections():
for( const auto& v : categories )
{
...
auto it = sections.find( v.first );
ImGui::TextDisabled( "(%s)", RealToString( it->second.size() ) );
...
}
sectionsDescription is a superset of sections's keys: ProcessSectionSetup
(server/TracyWorker.cpp:7484-7496) inserts into sectionsDescription only,
while ProcessSectionEnter (server/TracyWorker.cpp:7416-7454) inserts into
both. A category set up via TracySectionSetup that has no TracySectionEnter
events yet (or a saved trace containing such a category) will be in
sectionsDescription but not in sections. find returns end() and
it->second.size() is undefined behavior (likely crash).
The current "parents" mode of operation is "was this symbol executing".
The new name for the maps reflects that.
There should also be "was this symbol reached" (both recursive and non-
reentrant) modes.
Added a "Sort" button to the Flame Graph view, allowing users to sort threads based on group hints, thread names, and IDs. Updated the child window to always show a vertical scrollbar for better usability.
Currently, the profiler will build against the git NFD, but link it as a
shared library. Since libnfd is not installed when building Tracy as a
distro package, it will end up actually depending on and running against
an older distro-provided NFD, hitting an unresolved function error due
to the newly added NFD function in git.
Other deps fetched with CPM are linked statically, avoiding this
problem.
