Windows?
There were some problems with creation of temporary directories/files. 
If I remember correct, from time to time (huge project, fast computer) 
collision occured when compiler (or make?) tried to create temp 
directory with the name that was still in use. It happend with early 
version of gcc 4.x? then it was fixed. I don't know does this problem 
exists in older version  of gcc. I guess, CLT guys would answer better:-)
