ESP32: CORRUPT HEAP on send

[raisinbread]

Been having some good luck on Arduino, but needed to move to ESP32. Compiles fine, but when I try to send/emit, I get an error and a crash.

Code:

IrSender *sender = IrSenderPwm::getInstance(true);
sender->send(binaryToTxIrSequence(signalData), CARRIER_FREQ, DUTY_CYCLE_PERC);

binaryToTxIrSequence() just takes a binary number and creates some spaces and marks for me and returns an IrSequence. When this code gets executed, I end up with this:

CORRUPT HEAP: Bad head at 0x3ffb1e6c. Expected 0xabba1234 got 0x3ffc003c
abort() was called at PC 0x400838a1 on core 1

Rebooting...

I've been using the camera on my phone to see if I can see the IR LED flashing, and it still seems to do so. For some reason it seems like after the IrSequence is sent, things crash. The code works fine on an Uno - wondering why I'm getting crashes here.

New to ESP32 so maybe there's some configuration I'm missing, but wondered if others had seen this or have any clues on how to fix.

Does the example IrSendPwm work?

Please post the entire sketch.

It does - I think it might be the way I'm constructing the IrSequence. I'll keep playing with it.

Yes - was an issue with IrSequence creation. Seems to work now.
