gfx/gl2: fatal error: concurrent map read and map write #150

Closed nwidger closed 8 years ago

nwidger commented 8 years ago

I'm seeing fatal errors in gfx/gl2 due to the new concurrent map read/write checks added in Go 1.6. This is a stack trace from nintengo:

$ go build && ./nintengo Legend\ of\ Zelda,\ The\ \(U\)\ \(PRG0\)\ \[\!\].nes

Support for this will be removed in a future release. Also, this makes the host incompatible with version 3 audio units. Please transition to the API's in AudioComponent.h.

I have a fix, it was a bug in both nintengo and Azul3D. Will send out soon.

Excellent, two bugs with one issue, what a deal!
