[Bug c/31984] New: Infinite loop (eating all mem) compiling xorg 1.3.0.0
While compiling xorg-server-1.3.0.0/hw/xfree86/scanpci/xf86ScanPci.c gcc goes
into an infinite loop eating up all memory. Compiling flags were: -g -O2
(defaults).
Output (with virtual memory limited to 512000k) follows.

[Bug tree-optimization/30052] [4.2 Regression] possible quadratic behaviour.
--- Comment #20 from m dot vegni at it-systems dot it 2007-05-18 23:31 --- Subject: Re: [4.2 Regression] possible quadratic behaviour. Testsuite ran on i686-pc-linux-gnu without failures (i've enabled c and c++ only). xorg-server now compiles as well. The patch deserves more testing but IMHO it's in the right direction.
