Re: bizarre g++ behavior after reinstalling cygwin

I just reinstalled cygwin on my laptop (running winXP) and g++ is acting

The code that has been working fine for thepast 2~3 months no longer

get trapped in loops indefinitely.

We'll need to see actual code snippets that misbehave before we can help. However, judging by your example below, I can guess that most of these are against the general C++ coding practices. GCC 3.4 is much stricter in that regard than previous versions, and does not necessarily try to make sense of such code, which is probably what's happening in your case. Did you try compiling with "-Wall"?

Digging in I found that none of the "i=i++" calls inside for-loops work.
I have never heard of anything of sorts, still changes ++ to +1, this
fixed the loops, but apparently there are still problems...

"i=i++" is either a no-op or nonsense, depending on the interpretation. You should either use "i=i+1" or "i++" (those should be equivalent in modern compilers).

please help, have i lost my mind?

That's for you to say, but I suspect your code would benefit from some review and rewrite. Google for "C++ code style guide".
