No, I don't think it's a XSLPattern crash, but still showed fixme should be
fixed probably.

The reason it crashes is another case when developers ignore arguments type.

trace:msxml:domdoc_createProcessingInstruction (0x14a570)->(L"xml"
L"version="1.0" encoding="UTF-8"" 0x32ec80)
...
=>0 0x7ecd26cf SysAllocStringByteLen+0x5f(str="", len=0x8455355)

Processing instruction body passed as WCHAR string instead of be properly
allocated BSTR.

This could be verified with tracing passed pointer and +relay to catch all
SysAllocString() return values.

Fix is simple, already done for some methods with tests.
