is there some known regression with gcc on armel?
I upgraded a test machine (buffalo linkstation pro/Marvell Orion5x) from
buster to bullseye, then I rebuilt the dspam[*] deb (since it's been
dropped by debian since buster, I did the same there).
The newly built binary doesn't start, complaining of a configuration
error, the binary built with buster still works.
I traced the execution with gdb and it doesn't make sense: a function is
called with a pointer to the configuration struct but inside the
function it is null.
I then recompiled it with -O0 instead of the default -O2 and this time
it works (will try later with -O1).
I'm not very familiar with gcc, so do you know of any regression with
gcc optimizations on armel (maybe with some other package needing
special optimization options)?
Note that I had to add the "-z muldefs" option to the linker, but I
don't think that's the problem (the null I saw wasn't a global variable
but a parameter).
[*] I know it's a dead project, but it still works and it is
surprisingly effective and lightweight on such an under powered machine.
