i am using fedora 8 and until last few days, it was working flawlessly. but now i am facing a strange problem. i detect this problem first while trying to compile a f90 program using ifort. it was not doing anythin...not creating executable, not giving error....just not doing anything. then i found that even gcc -v is hanging......and responding after long(really long time say 2min) time and sometime not at all and also disabeling the terminal. even strange thing is once in a while every thing is working fine....but this good time lasts only for few seconds. can anyone suggest me to do some check to found what is going wrong? $ gcc -v Using built-in specs.
