gcc 4.4.3 exhausted all memory(3.2G) and got stuck in an infinite loop:
gcc-4.4.3 -O3 MTest-1.c
while gcc-4.4.1 works fine with the same option.

gcc-4.4.3 config options:
^_^ $../../exe/bin/gcc -v
Using built-in specs.
Target: i686-pc-linux-gnu
Configured with: ../src/configure
--prefix=/home/wuwei/testbed/gcc-4.4.3/obj/../exe --enable-languages=c
Thread model: posix
gcc version 4.4.3 (GCC) 

and config info of the compiler which compiled gcc 4.4.3:
^_^ $gcc -v
Using built-in specs.
Target: i486-linux-gnu
Configured with: ../src/configure -v --with-pkgversion='Ubuntu 4.4.1-4ubuntu9'
