I honestly don't remember the circumstances that caused me
to add this -- it's been sitting in my sandbox for a while.
Thought it would be better to offer it up than to throw it
away...




Wouldn't a message like this be symptomatic of failure
in GDB's executable date detection code, or in the executable
production bits?



If I understand it, we get that message precisely when gdb's executable date detection code works as intended. It discovers that the executable's modification date has changed, and therefore re-reads the symbols.


But when would that happen while running the testsuite?
I would expect that the executable is left alone between run
commands - if GDB thinks it needs to re-read symbols between
run commands on the same executable, that seems like a GDB
bug and a performance loss to boot.

OK, let's drop it then. As I say, I don't remember why I did it in the first place.
