Subject: [Bug c/43811]  New: infinite & memory leak when using -O3 option
Date: Tue, 20 Apr 2010 02:40:00 -0000	[thread overview]
Message-ID: <bug-43811-19053@http.gcc.gnu.org/bugzilla/> (raw)

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

and config info of the compiler which compiled gcc 4.4.3:
