fix #12379 FN: uninitvar due to line splicing

[clock999]

https://trac.cppcheck.net/ticket/12379

No warning is given, because Cppcheck does not remove the next line after // some comment\ properly:

#include
#include
#include

void f()
{
std::size_t i;
const std::vectorstd::string v{"4", "2"};
// Some comment
for(i = 0U; i < v.size(); ++i)
{
std::cout << v[i];
}
}

Since this is a change in simplecpp, please open a PR at the upstream project https://github.com/danmar/simplecpp
See danmar/simplecpp#337
Also, a test is needed there.

Hi CHR, I will submit PR to project simpleapp. What do you mean by "Also, a test is needed there"? Do you mean that I need to code test cases and submit them together with the fix code? Many thanks!

Hi, I am not sure if there is a problem with the unit tests on the simpleapp project. I posted the details here: https://sourceforge.net/p/cppcheck/discussion/general/thread/37c6eba151/
Could you please help take a look? Thanks!
