Bug #506713 in gcc-4.3, which has just been fixed in unstable, results
in incorrect code generation in SPARC shared libraries. I identified
this as the cause of bug #490999 in kicker, but it presumably affects
other shared libraries and will require binNMUs to fix. However, doing
a binNMU for every package that builds a shared library would obviously
take a lot of buildd time and would likely make a mess of dependencies.
I do not know exactly what is the general pattern for the wrongly
generated code, but I will try scanning for shared libraries containing
the pattern:
save %sp, offset1, %sp
/* up to 10 instructions */
ld [ %sp + offset2 ], reg
where offset1 + offset2 < 0 and reg is any register.
