Heap functions not weak for AVR teensy boards

[xxxajk]

Just like the title says, malloc and friends can not be over rode by a library.
The same code I am using works fine on all AVR based Arduino boards.
Without this fixed the advanced features of UHS30 will be unusable on Teensy 2.0 and Teensy 2.0++.
I know you are VERY busy Paul, but a fix in the next TeensyDuino would be nice.

Prerequisite libraries: https://github.com/felis/UHS30
source code: https://github.com/felis/UHS30/blob/master/libraries/UHS_BULK_STORAGE/examples/USB_HOST_SHIELD/TEST_BULK/TEST_BULK.ino

Here is the (obvious) link error output:

I'm not sure if Paul will see this here. Chuck it over in the Suggestions thread. I'm personally all for this

 

[xxxajk]

I could just email him directly too...

Or you could send a pull request with the specific change you want.

Yeah, I know... Just a bit busy at the moment, making boards
