z390 generated an invalid END record in object file

[marcels68]

The entry point address is not blank (0x404040) so it contains an entry point address within a section.
The ESID field must contain the ESID number of the section that the address is within. Instead the ESID number is 0x0000, which is not the number of any section listed in the ESD record. Thus it is impossible to determine the entry point address.

ESD and RLD records generated by z390 each contain only one item and each TXT record only contains 16 bytes.
The result is instead of 49,760 bytes, U0DM71P is 182,400 bytes, a factor of 3.7 times larger than it needs to be.
This will slow the loader significantly.

I downloaded the zip file attached above (U0DM71P.zip) but it contains no readable source code.
It seems to be the EBCDIC version of the source code.
If the file is converted to Ascii, I'll be happy to try and recreate the symptoms described above.
