I cannot reproduce on the SPARC/Solaris 9 machine I use. Please provide as
many details as you can on the OS, the linker, the assembler, GCC, GDB and so
on.

Here's the verbose output from the compiler driver:
$ gcc -v t.c
Using built-in specs.
Target: sparc-sun-solaris2.9
Configured with: /build/sebor/gcc-4.1.0/configure --enable-languages=c,c++

I'm told that the fault is due to a known problem in the Sun libc:
6372620 printstack() segfaults when called from static function
It this doesn't provide sufficient detail to work around the bug in gcc

Maybe it's one of the runtime library functions that's static (maybe _start?).
The diff between the two .s files is empty.

Here's what I learned from Sun:
Here is the test case from that bug report:
[Makefile]
main: main.o libshibby.so
gcc -L. -lshibby -Wl,-R. -o main main.o
main.o: main.c
gcc -c -o main.o main.c

Here is the test case from that bug report:
I gather than compiling with -fPIC and/or calling printstack from a shared
library is necessary to trigger the bug, which is not what you reported. At
this point

If this is due to a Solaris bug it would be great if gcc could work
around it.
And this attitute is wrong. Did you file this with Sun yet? If not, you
should say the same thing, if this

I'm not sure what you find wrong with my attitude but yes, I did send Sun a
note about it pointing them to this problem report.
