_______________________________________________________
Details:
There is a call to memchr() in Pexecute (in search.c) which is not checked for
NULL return value, and as a result can crash the program.
The attached patch fixes the problem. Note that the added test was not tested,
because I could not get the GNU Build System to re-build the build-files on my
system.
