"a custom control callback raised an exception"

Question

Hello all,
yes, there are several posts about this error message, but they are all pretty old (<2009) and the solutions didn't seem to work, so I'm starting a new thread.
I installed 2013sp1 last week and removed 8.5, 2010 and 2012 this morning. And now one of my projects won't compile. Other projects aren't impacted (I tested about 10 in two different workspaces).
When I compile, I get a popup box with "a custom control callback raised an exception" and it comes back as soon as I click it. I have to kill CVI. It's a project that compiled cleanly with CVI2012 (no warnings). I can open and save the UIR files with CVI2013, no problem. I also deleted the cws file, no change.
I generated a debug log (cleaned up a bit):

The last line gets duplicated every time I click the popup, so it's relevant.
Solved!

Hello and thank you for looking into this.
Indeed, I disabled the HTML generation and it compiled fine. I also tried XML and it works, although I don't know what to do with the resulting XML file.
Here's a code sample showing how I use the triple slash comments, but this is not an example that crashes. I'm trying to pin it down but it's a big interdependant project, so I can't remove pieces easily:
/// HIFN Write to USB. Use the USB_WRITE shortcut macro instead
/// HIPAR Endpoint / USB endpoint
/// ARRAY Data
/// HIPAR Data / Array to write
/// HIPAR Count / Number of bytes to write
/// OUT ErrorMsg
/// HIPAR ErrorMsg / Possible return error message
/// HIPAR FunctionName / For debugging
/// HIPAR Line / Line number for debugging
static int UsbWrite(int Endpoint, char Data[], int Count, char *ErrorMsg, const char *FunctionName, const int Line) {
