thread -> get_next_buffer_smart: memory read into buffer failed.thread

[MexikanoS]

$ sudo ptrscan -a 0x10a4d750 -w first_map.pscan client
thread -> get_next_buffer_smart: memory read into buffer failed.thread -> get_next_buffer_smart: failsafe memory read into buffer failed.

Got all privileges; process is able to be proceed. I waited for couple of minutes after this error occured but nothing happened, so seems like EOL without shutdown. Any description on the error would be nice.

I'll look into it shortly. In the meantime, try building with 'make scan_debug'. This should dump the internal tree as it is being built.

And so on.. xd

Latest release v0.0.3 will output errno (via perror) to help identify precisely why this is occuring. It requires Libpwu v0.1.4. Hopefully it's just an EAGAIN / EWOULDBLOCK.

I have not been able to replicate this error on any of my machines while scanning similarly large processes. If you're available to look into this more closely, I'd like to run through your example together. I am @vykt on Discord.

Thanks.

Fixed in indev branch.
