Giving code:

const int Count = 100'000;

int main()
{
/* whatever */
}

VA basically stops working when editing anything after first line, no snippets, no suggestions.
Remove the digit separator in the first line, everything back to normal.

If the first line was written as:

const int Count = 10'000'000;

Everything is fine.

This bug was found in version 10.9.2086
Probably because VA treat the separator as the beginning/closing of a character literal.

Which IDE and version of VA are you using?

This code does not compile for me in VS2013, but it does compile in VS2015. I did not know this was possible, learn something new every day.

case=86379

As a temporary work around, have you considered changing the const to read:

const int Count = 100 * 1000;

which is still fairly clear, and means the same. This is how I have always done large numbers, so I can be clear on how large the number is.

Currently only VS2015 supports digit separator, so this code won't compile under VS2013 and below. This is a C++14 feature.
I have tested it under VA 10.9.2076 and 10.9.2086, both showing the same symptoms.

This is a "bug" in VA, we have not yet added support for this new syntax, but are looking to do so. This is covered by:

case=86379

and this thread should be updated when this has been fixed, and supported has been added.
