 * The ebuild phase 'unpack' has exited unexpectedly. This type of behavior
 * is known to be triggered by things such as failed variable assignments
 * (bug #190128) or bad substitution errors (bug #200313). Normally, before
 * exiting, bash should have displayed an error message above. If bash did
 * not produce an error message above, it's possible that the ebuild has
 * called `exit` when it should have called `die` instead. This behavior
 * may also be triggered by a corrupt bash binary or a hardware problem
 * such as memory or cpu malfunction. If the problem is not reproducible or
 * it appears to occur randomly, then it is likely to be triggered by a
 * hardware problem. If you suspect a hardware problem then you should try
 * some basic hardware diagnostics such as memtest. Please do not report
 * this as a bug unless it is consistently reproducible and you are sure
 * that your bash binary and hardware are functioning properly.

That is the line:
                 STRICT_COUNT=$((10#${STRICT_COUNT} + 1));
Comment 1 Ionen Wolkens 2020-12-29 00:43:20 UTC
This is bash-5.1 specific, stable bash works fine.
Comment 2 Ionen Wolkens 2020-12-29 12:40:08 UTC
Actually I'm amazed this worked at all.

For some reason bash-5.0 let this goes by and echos 1

   testfunc() { local SC; echo $((10#${SC} + 1)); }

I assume the intend here was for ${#SC}? Not that I've reviewed the logic. This is also used in another location written the same way.

kernel-2.eclass bug rather than git-sources anyway.

Nevermind this, I just learned what arithmetic base in bash
is (never needed this construct before). That aside, SC being
unset looks like the problem, e.g. $((10#+1))
