mov dword ptr[eax], 1 is invalid in Hopper Disassembler?

Question

I'm trying to Patch a 32bit ELF file with Hopper disassembler

The ASM code I use is like the following

mov dword ptr [eax], 15

But when I enter that expression, Hopper consider it as invalid? It works perfectly in IDA and I'm not sure why

Any ideas?

@blabb It's code section. mov dword ptr ds:[eax], 15 does not work either — daisy, Mar 03 '18 at 09:16
I've just checked Hopper v4 and have no issues with assembling this instruction. There has to be something else. Can you post the binary? — Paweł Łukasik, Mar 04 '18 at 13:32
@PawełŁukasik I'm running V3 version .. Guess that's the problem — daisy, Mar 04 '18 at 15:30
@daisy try get in touch with the author. Last few times I contacted him, he was very responsive. — 0xC0000022L, Jun 17 '18 at 20:00

I've checked version v3 and yes, it does not work with such instruction and it does work in v4. There are few bug reports that might be related to such issues.

FS#155
FS#162

Unfortunately I couldn't find if there is any workaround for this apart from installing a latest one.
