glBufferSubData & sTRACE_WEBGL_CALLS

[Dieter Weidenbrück (dweidenbrueck)]

Hi,

it looks like there may be an issue with glBufferSubData tracing.
Take any example using glBufferSubData and compile with

-sMIN_WEBGL_VERSION=2

-sMAX_WEBGL_VERSION=2

So far, so good.

Now add

-sTRACE_WEBGL_CALLS=1

it looks like the call is using a wrong hook during tracing. It misses the last parameter.
This leads to a buffer overflow error.
Switching off tracing returns everything to normal.

The problem did not exist when I was using WebGL version 1.

Thanks for any idea how to get around this.

This looks like an issue with `hookGLFunction` in `library_webgl.js`.   Would you mind opening a bug?

cheers,

sam
