Sure there is: win32error.c produces exactly that message if its
mapping table has no entry for the Windows error code.

According to

https://docs.microsoft.com/en-us/windows/win32/debug/system-error-codes--0-499-?redirectedfrom=MSDN

code 38 decimal is ERROR_HANDLE_EOF, "Reached the end of the file.",
which indeed is not in the doserrors[] table.

But that just deepens the mystery --- if we hit an EOF, why wasn't
that handled through more-normal channels?  We still need to know
what that function was trying to do, and whether any non-core
C code was involved.
