Bug ID: 127409
Summary: gcc's .gdbinit hooks don't load the libstdc++
pretty-printers
Product: gcc
Version: 17.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: rearnsha at gcc dot gnu.org
Target Milestone: ---
gcc statically links against libstdc++, so the auto-loading facility for
loading the c++ library pretty-printers into gdb never get called. The result
is that when debugging C++ elements like iterators they don't display properly
unless this stuff is all manually loaded. In particular printing an iterator
generally only shows the C++ internals rather than the templated element.
(gdb) p mpi
$12 = {_M_node = 0xffffffffdea8}
(gdb) p *mpi # Should print the templated iterator element type.
Attempt to take address of value not located in memory.
We construct a .gdbinit in the target build directory - this code should be
augmented with the relevant hooks to load the appropriate pretty-printers for
the version of libstdc++ that we have been linked against.
