DB2 FOR LUW / DB2FORLUW / A50 - DB2

When using the DB2MQ.MQRECEIVEALL (non-federated) routine with
KEEPFENCED=YES, it can intermittently trap/abend producing an
SQL0430N error.    With coredump enabled we can see the
following functions in its stack:

Segmentation fault in iconv at line 845 in file "" ($t1)
could not read
"../../../../../../../src/bos/usr/ccs/lib/libiconv/iconv.c"
(dbx) where
iconv(cd = 0x0000000110286eb0, inbuf = 0x0fffffffffff80c0,
inbytesleft = 0x0fffffffffff80c8, outbuf = 0x0fffffffffff80b8,
outbytesleft = 0x0fffffffffff80d0), line 845 in "iconv.c"
