To me it does strongly look like a memory corruption.
* There is absolutely no hint where the string
"/src/m3/libs/m3core/LINUXLIBC6/" could permissibly come from.
* "/src/m3/libs/m3core/LINUXLIBC6/" has been a previous working
directory but should be present nowhere in memory by now.
* The error occurs in a rather nondeterministic manner.
* It does not occur on startup but right after some time of working.
P.S.: Please do not wipe this under your table. It has occured more than
once.

extglob on
This is in a fact strange since the error does not seem to occur in a newly
opened bash session:
** Konsole #1 **
> printf -v var "%b" @(hugo); echo "x${var}x"
xx
Nevertheless I have not shut my computer down since I have reported this bug
and the konsole where the nullglob error occurs is still open (Konsole #0)!
** Konsole #2 **
> printf -v var "%b" @(hugo); echo "x${var}x"
x@(hugo)x
> echo "x${var}x"
x@(hugo)x
Very strange!! I have not found out yet when it does occur and when not.
The error has now arised in a another konsole session:
** initial Konsole #0 (still open; konsole of initial bug report) **
> printf -v var "%b" @(hugo); echo "x${var}x"
x/src/m3/libs/m3core/LINUXLIBC6/*.@(m3|i3|ig|mg)x

Note: In this example the value of var is corrupted only if it is used
within the same line of code!!
In #2 var keeps the wrong value.
