when compiling the new ghc pre-releases made my gcc 2.95.3 die with "internal compiler error", I tried to compile it with gcc 3.4.3 (or rather, I thought it compiled with 3.4.1, and when that died, compiled+installed gcc 3.4.3, tried again, say it die again and only then noticed it was actually still using 2.95.3 ;) but had quite some difficulty to actually get it to compile with, in my case, /usr/local/bin/gcc3
When using the following command-line
CC=gcc3 CXX=g++3 nice ./configure --enable-hopengl --prefix=/var/tmp/ghc --with-gcc=/usr/local/bin/gcc3
stage1 still used gcc 2.95.3 to compile stage2 (okay, for --with-gcc that's documented)
Really? --with-gcc should set the gcc for stage1, AFAIK. Is there a bug here?
I've noticed gcc 2.95 crashing on my FreeBSD box too. I should look into whether there's a workaround, otherwise we're hosed on FreeBSD 4.x.
This is a known problem in all the 3.x compilers, and also occurs, although less often, with 2.9x versions. I've seen no difference in frequency comparing FreeBSD to Linux and NetBSD.
The only solution, which is of course highly annoying, is to simply restart the make. For whatever reason this always works, sometimes until the end of the build, and sometimes until some other crash. My theory is that it is related to the temporary files that gcc creates, mostly for templates.
While a royal PITA, the resulting code is correct.
A known problem? Is there any open bug in the gcc bug database I can look at?
There has to be one, because the problem occurs when you compile gcc with gcc. I'll look for a specific bug report. It happens much more frequently with 3.x than with 2.95, in my testing, but that was not a test of compiling Haskell, so I have no frequency information, specifically. The compiler is broken, but since you can recover by restarting the make, it isn't horrible, just almost horrible. The other problem for the gcc people is the fact that it occurs randomly. The behavior has changed; 3.4 will crash in a different place than 3.3. If the program is large enough, it will happen.
