MSSIPOTF_E_OUTOFMEMRANGE

A directory range is outside the font file

MSSIPOTF_E_OUTOFMEMRANGE concerns a byte range referenced by the font, not ordinary process-memory exhaustion. OpenType table records describe each table with an offset and a length. If the checker cannot keep that range within the file it mapped, it must stop before treating arbitrary bytes as font data.

A truncated download, a damaged table directory, an offset rewritten after a table was removed, or an arithmetic overflow in a font producer can all lead to this condition. It differs from MSSIPOTF_E_FILETOOSMALL: this code points to an attempted reference outside a valid mapped range, while the latter specifically identifies a final table extending beyond end of file.

How to investigate

Preserve the original file and compare its byte length and hash with the source artifact before editing.
List the table directory with ttx -l or another independent parser, then check every offset + length against the file size.
Rebuild the font from its source rather than patching offsets in a signed binary; a repaired layout also changes checksum and signature material.
