the ice only occurs when the code is compiled with -O2. Other values for -O don't
give the ice.
This bug is also in 3.4.0.
Gcc 3.3 compiles fine.

I cannot reproduce this with any compiler on i686-pc-linux-gnu, maybe is it
target specific?
DBK, would you please post the compiler log (adding -v to the command line)?
Eric, I guess that if this is a sparc-specific bug, you can easily confirm this
bug?

I cannot reproduce the bug on i686-pc-linux-gnu neither. I think it's sparc
specific.

I can confirm this on sparc-sun-solaris2.9. It requires -mcpu=v9
though which is interesting because the crash seems to happen in
apparently arch independant code (see backtrace below):
I use the following cleaned up testcase:
/* Compile with -O2 -mcpu=v9 */
int bar(void);
void baz (void) __attribute__ ((noreturn)); /* noreturn is required */
int foo;
void f (void)
{
while (bar ()) {
switch (1) {
default:
baz ();
}
}
}
Program received signal SIGSEGV, Segmentation fault.

This is most likely a latent bug on the mainline also but as far as I can tell there is no way to hit this
crash.

Sure, although a bit late it seems :-) Note that I don't need to specify -mcpu
to get the SIGSEGV.

Indeed. The original testcase (first attachment) does require -mcpu=v9
to trigger the ICE here whereas the simplified version (comment #4) doesn't.
