ex45978-extraLinkTableSheets.xls is a cut-down version of attachment 22561.
The original file produces the same error.
This bug was caused by a combination of invalid sheet indexes in the EXTERNSHEET
record, and eager initialisation of the extern sheet references. Note - the workbook
has 2 sheets, but the EXTERNSHEET record refers to sheet indexes 0, 1 and 2.
Offset 0x3954 (14676)
recordid = 0x17, size = 32
[EXTERNSHEET]
numOfRefs = 5
refrec #0: extBook=0 firstSheet=0 lastSheet=0
refrec #1: extBook=1 firstSheet=2 lastSheet=2
refrec #2: extBook=2 firstSheet=1 lastSheet=1
refrec #3: extBook=0 firstSheet=-1 lastSheet=-1
refrec #4: extBook=0 firstSheet=1 lastSheet=1
[/EXTERNSHEET]
As it turns out, the formula in question doesn't even use externSheetIndex #1 - it
uses #4, which resolves to sheetIndex 1 -> 'Data'.
It is not clear exactly what externSheetIndex #4 would refer to. Excel seems to
display such a formula as "''!$A2", but then complains of broken link errors.
