opatch[432]: -d64: not found.

This is only happening on HP boxes.

Whenever I type any opatch command, the opatch runs fine but it shows below line at the beginning of output:

./opatch[432]: -d64:  not found.

I wanted to see what does that mean. opatch has below at line# 432

..
..
JRE_MEMORY_OPTIONS=${MEM_ARGS} ${JVM_D64}
..
..

Putting double quotes around ${MEM_ARGS} ${JVM_D64} fixed the issue.

e.g.

..
..
JRE_MEMORY_OPTIONS="${MEM_ARGS} ${JVM_D64}"
..
..

BTW, this is not just limited to HP-IA, this also happened on HP PA-RISC.

Also realized that this is fixed in new version of opatch i.e. OPatch Version: 11.1.0.9.4
