Thanks for beta... :-)
... quick test on SuSE Linux 12.1/AMD64/gcc4.6.2 with _and_ without
-O2 (which means optimiser settings are not relevant) triggers the
following testsuite failures:

Problem seems to be that |sp| is |NULL|... which triggers the code
dump (Linux has no "coreadm" ... ;-( )...
Next crash is this one:

No coredump is produced... I have to dig later why this happens...

The _really_ frustrating part is that if I run the tests manually with
"shtests" I get no failures. Same happens if I use a "ksh" build with
libshell&&libcmd&&libdll&&libsum&&libast linked statically.
Finally... there are two new warnings:
