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.
