[LDVSOFT]

I have manually specified public adrress, still crashes on first client.

[wfjsw]

I swapped -p and -H then it works(sort of)

[p1ratrulezzz]

Haha, yes there is a confusing thing about it. -H is the address which actually used to listen for incoming connections (the port you put in the port field on telegram client) and -p used for something internal. On many servers if you have nginx or any web server set up already with https you can't set it to 443 as it will be already binded by nginx or apache. Just start it with something like -H 6889

[LDVSOFT]

@p1ratrulezzz Crashes for me on unoccupied unpriviledged port, though!

[wfjsw]

@p1ratrulezzz no both two port is not occupied and I am using port > 30000
gdb didn't show anything helpful.

[stanislavvv]

Confirm crash at start under Debian 9 (gcc 6.3).
It is not "Address already in use" error.

[wfjsw]

Well, I found the code is highly targeted on Intel while I am using AMD...

[stanislavvv]

I build on desktop and use virtualized cpu on target. How i can switch off any cpu type locks?

[wfjsw]

I think crc32.c and crc32c.c are the biggest hells.

[coolermister]

Have the same)

[stek29]

@wfjsw @stanislavvv does it work if you pass --crc32c ?

[wfjsw]

@stek29 nop I got illegal instruction

[stanislavvv]

same result with --crc32c

[stanislavvv]

Sorry, forgot git pull and make clean && make
Now it's work.

[wfjsw]

🤔 I still have it. weird
let me gdb it

🤔Threads?

[wfjsw]

remove -O3, changed march it finally runs :/
well I run it with proxychains and seems no connection is made through my tunnel.

[stek29]

@wfjsw wasn't just removing the march enough?

[wfjsw]

@stek29 didn't remove march but changed it to native

[coolermister]

Confirm @wfjsw. Changed march to native, O3 to O2, and it works)

[wfjsw]

@stek29 If we remove march crc32.c won't compile.
