 Here's the output of g++ -v if it helps:

Thanks, but we still need the preprocessed sources...

I don't remember I ever used this funky __builtin_expect.  
valarray is improving everyday :-(

You most likely did not but assert did :).

So on solaris assert is defined as
(void)((operand) || (__assert (),0) );

(In reply to comment #1)

This was gcc 4.1.0 on sparc-sun-solaris2.9.

Hi. In fact, I'm getting the same as Andrew on x86-linux, x86_64-linux and
powerpc-darwin. Seems a really weird target-dependent issue, I hope Eric can
help, a minimum of debugging, a backtrace (thanks in advance, anyway)

No SIGSEGV for me with 4.1.1:

gax% ./pr30280
Assertion failed: a == false, file pr30280.C, line 7
zsh: IOT instruction (core dumped)  ./pr30280

Please provide the missing info as per http://gcc.gnu.org/bugs.html

Regardless of whether the program aborts with SIGSEGV or SIGABRT, the point is
that it should either not compile or it should run succesfully to completion.

Here's the output of g++ -v if it helps:

Yes, the crazy thing is that apparently the snippet *compiles* only on
sparc-solaris (and shouldn't, of course).
