Are you using ESP8266WebServer ?

I've done some fixes on that yesterday, I've submit a PR to IGRR, waiting for merge.
https://github.com/esp8266/Arduino/pull/753/
(But you can grab the fixes and manually patch your environment)

I looked at your fixes, and it should address the issues that I am seeing. I'll try tonight.

I am not familiar with the under workings of the ESP8266, but depending on the length of the binary data being sent, does the watchdog need to be kicked in the loop?

Thanks,

I presume the _client.write() is already handling that with a yield() while a packets are sent.

I replaced 3 files in my environment, built, and get the following errors:
ESP8266WebServer.cpp
ESP8266WebServer.h
WiFiClient.cpp

Maybe you have a newer WiFiClient.h?

This was one of my contribution that was been merged in the main tree 3 weeks ago.
See commit : https://github.com/esp8266/Arduino/comm ... f5adcc4e6f

If you install staging, you will get it. Otherwise, you will need manual merge there too.
