Spire.Xls / Spire.Doc crash when including images

[ericcampbell]

Unfortunately, we've discovered another bug in Spire.Xls 13.9.0 & 14.7.3 / Spire.Doc 12.71. (or some combination thereof). In some circumstances, generating a .doc file followed by an .xlsx file will result in a crash. In our testing, we found that generating a Word file, then converting two or more Excel files to a pdf, then generating another Word document results in an unrecoverable (not caught even with a bare try / except) crash. The trick also seems to be that both file kinds need to have images included in them.

This bug is present when using either of Spire.Xls 13.9.0 or 14.7.3.

Code: Select all

We have created an MWE at https://github.com/EricRobertCampbell/s ... -excel-mwe. Please let us know if there's some additional information we can provide to help expedite this process.
