Ensure that the int64_t offset value, which ultimately comes from an int64_t value in gencode() (assemble.c:1906), is completely written to the temporary buffer, instead of merely its least significant 32 bits. Prior to this change, WRITELONG was used instead of WRITEDLONG, which resulted in add_reloc being passed an int64_t "reloff" whose least significant 32 bits were those from the aforementioned offset value, and whose most significant 32 bits were stack garbage from "mydata". This led to get_closest_section_symbol_by_offset() attempting to search for extremely large values of "offset" among the symbols in "syms", which meant that the last symbol with a matching section number would always win the symbol search. In effect, this clobbered the resultant relocation information, such that all entries would be resolved with the same symbol.

NASM, the Netwide Assembler.
Many many developers all over the net respect NASM for what it is
- a widespread (thus netwide), portable (thus netwide!), very
flexible and mature assembler tool with support for many output
formats (thus netwide!!).
Now we have good news for you: NASM is licensed under the "simplified"
(2-clause) BSD license. This means its development is open to even
wider society of programmers wishing to improve their lovely
assembler.
The NASM project is now situated at SourceForge.net, the most
popular Open Source development site on the Internet.
