gcc-3.4.3-20050110-r2 gives me internal compiler exceptions all over the place; it's pretty bad. Example: double bar() { return 42; } double foo(int i) { double a = 0; if(!i) return 0; double b = bar(); if(b == 0.) return 0.; return a; } gcc -O2 try.c try.c: In function `foo': try.c:14: internal compiler error: in try_split, at emit-rtl.c:3343 Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://bugs.gentoo.org/> for instructions. Preprocessed source stored into /tmp/ccUheKJF.out file, please attach this to your bugreport. The above code ICEs for me with CFLAGS="O" and "O1" on "vanilla" profile, and for "O", "O1" and "O2" on "hardened" profile. The same error occurs on both athlon-xp and pentium4 machines -- those are the only two architectures I have handy. A list of packages that I cannot compile (due to ICE in in try_split, at emit-rtl.c:3343) includes : abiword-2.2.5, gimp-2.2.6, openoffice-ximian-1.3.9-r1, and a bunch of other stuff. gcc was compiled with USE="(-altivec) -bootstrap -boundschecking -build -debug +fortran -gcj +gtk +hardened (-ip28) (-multilib) -multislot (-n32) (-n64) +nls -nocxx -objc -static (-uclibc)" Reproducible: Always Steps to Reproduce: 1. emerge gcc-3.4.3-20050110-r2 2. put the above code listing into file try.c 3. gcc -O1 try.c Actual Results: internal compiler error: in try_split, at emit-rtl.c:3343 Expected Results:

Hm... on both machines, gcc-3.4.3-20050110-r2 was so broken that it couldn't even compile itself. So I used an old gcc-3.3.5 binary to recompile gcc-3.4.3-20050110-r2, and now it seems to work perfectly. I have no idea how this bug came about -- especially on two different machines. My guess is that the bug must have originated in whatever compiler I had used to originally compile gcc-3.4.3-20050110-r2 (presumably, an earlier version of gcc-3.4.3). Has anyone else who is using 3.4.3-20050110-r2 experienced anything like this?
