Find+fix steps that were performed:
1. Find all 'add' instructions that compute "eof".
NRV run-time decompressors ignore srclen, so 'add' can be ignored for them.

$ cd upx-devel4/src/stub
$ grep -sr 'add.*eof' src  |  grep -v 'nrv2._d.*.S'  |  sort
src/amd64-darwin.dylib-entry.S:        addq src,lsrc; push lsrc  // &input_eof
src/amd64-darwin.macho-entry.S:        addq src,lsrc; push lsrc  // &input_eof
src/amd64-linux.elf-entry.S:        addq src,lsrc; push lsrc  // &input_eof
src/amd64-linux.elf-so_entry.S:        addq src,lsrc; push lsrc  // MATCH_05  &input_eof
src/amd64-linux.elf-so_main.c:            void *mfd_addr = Pmap(0, sizeof(code), PROT_READ|PROT_EXEC, MAP_PRIVATE, mfd, 0);
src/amd64-linux.shlib-init.S:        addq src,lsrc; push lsrc  // &input_eof
src/arch/amd64/lzma_d.S://      addq src,lsrc; push lsrc  // &input_eof
src/i386-expand.S:    add src,%ecx; push %ecx  // MATCH_52  eof_src
src/i386-linux.elf-so_entry.S:        add src,lsrc; push lsrc  // MATCH_05  &input_eof

2.  Case-by-case inspection

src/amd64-darwin.dylib-entry.S:        addq src,lsrc; push lsrc  // &input_eof
    restoring 'subq' is added in this commit

src/amd64-darwin.macho-entry.S:        addq src,lsrc; push lsrc  // &input_eof
    restoring 'subq' is added in this commit

src/amd64-linux.elf-entry.S:        addq src,lsrc; push lsrc  // &input_eof
    a restoring 'subq' is already next

src/amd64-linux.elf-so_entry.S:        addq src,lsrc; push lsrc  // MATCH_05  &input_eof
    lsrc is dead for inlined nrv2b

src/amd64-linux.elf-so_main.c:            void *mfd_addr = Pmap(0, sizeof(code), PROT_READ|PROT_EXEC, MAP_PRIVATE, mfd, 0);
    .c code

src/amd64-linux.shlib-init.S:        addq src,lsrc; push lsrc  // &input_eof
    restoring 'subq' is already next

src/arch/amd64/lzma_d.S://      addq src,lsrc; push lsrc  // &input_eof
    comment that explains preceding actions in ELFMAINX; a restoring 'subq' is already next

src/i386-expand.S:    add src,%ecx; push %ecx  // MATCH_52  eof_src
    %ecx is dead

src/i386-linux.elf-so_entry.S:        add src,lsrc; push lsrc  // MATCH_05  &input_eof
    lsrc is dead for inlined nrv2b

0515be4334 LZMA on AMD64 had bug in calling sequence, leading to random exit(127) 
LzmaDecode randomly decided that the input had ended in the middle,
because of error in interface between ELFMAINX and the decoder.

Thanks to Kevin Gosse!
