Hello,
I have a user that is claiming gdb 7.2 does not work with C++ code
compiled with GCC 4.8.2. Gdb is provided by the system (RHEL 6) while
the compiler is one that I have provided. I'm still working with the
user on possible errors in their workflow with gdb, but I wanted to
investigate the limits of gdb's ability to keep working with binaries
compiled by newer compilers because I really don't know. What kind of
changes in a compiler would cause a particular version of gdb to no
longer work correctly with it? For example, I know that a change in
library format would probably require a new version of gdb, but does a
change in C++ specs require the same treatment?
I know that running with the latest version of gdb is a good idea to get
passed bugs and to net new features, but I'm trying to gain some sort of
intuition as to when a new version of gdb is necessary rather than just
a good idea.
Thank you all for your time and any help,
David
