Darn. Could you send a testcase that exhibits this
particular problem, so we can figure out whether this
a SPARC bug, or a profiling bug? Thanks,
Dara
P.S. If it's possible for you to check that this
occurs under linux/x86 on gcc 3.3 too, that'd be great.

Hi Dara,
I have tried compiling my application with "-fprofile-arcs
-ftest-coverage -O1 -g" using gcc 3.2.3 on solaris 2.8.
I no longer see the segfault during compilation.
However, the resulting image always crashes very soon after start up,
as follows:
Program received signal SIGILL, Illegal instruction.
0x0020592c in atexit@@SYSVABI_1.3 ()
I have not investigated further.
Simon.

Hello,
using gcc 3.2.3, 3.3 branch or mainline (20030509), and compiling the
testcase with -ftest-coverage, I do not get any ICE or segfault. Can
the submitter confirm whether they are still encountering this bug with
a current gcc version?
