2nd RESEND: Native build fails with malloc(): corrupted top size

(Resend without attachments now since this seems to be blocked by the list servers)

Hi!

Since around the 5.3 release, trying to build the SH kernel natively on
my SH7786LCR evaluation board under Debian unstable with a current gcc-9
toolchain fails with errors which seem to be generated by the C library:

Even with "make V=1" it doesn't become any more obvious what's going on:

From the build log history in Debian, it seems the problem showed first with 5.3-r5 [1].

However, I have tested this on an older 3.16.7 source that I have still on disk and
the problem reproduces there as well. The glibc version of builds where it fails and
where it didn't, seems to be identical [2, 3].

Does anyone have an idea what could be going on? I'm using the kernel configuration
as found in [4].
