Hi,
I'm the maintainer of DDD. I have some questions about the intent of
the gdb <MULTIPLE> breakpoints.
"info break" returns several lines for each breakpoint, e.g.
2.1 y 0x00007f2e2090c4d4 in
VoxelBuffer<char>::buffer_type() const
at ../VoxelBuffer.cc:95
2.2 y 0x00007f2e2090c540 in
VoxelBuffer<unsigned char>::buffer_type() const at ../VoxelBuffer.cc:95
2.3 y 0x00007f2e2090c5ac in
VoxelBuffer<short>::buffer_type() const
at ../VoxelBuffer.cc:95
The info page on breakpoints mentions 3 use cases: constructors,
templates, and inlined functions. In all 3 cases the multiple locations
are generated from a single source line. However, the "info break"
display shows a source file and line number for each location.
My question is: are there any circumstances in which you can get a
different source file or line for each location?
Thanks,
Peter Wainwright
