No.

[rathann@neoburza:/opt/builder/toolchain/bin]% file strip
strip: ELF 64-bit MSB executable, SPARC V9, version 1 (SYSV), dynamically linked (uses shared libs), not stripped

Not yet. I don't have gdb installed on that machine. I could, however,
send you the corefile itself. It's only 300k when gzipped.

Then I'm not sure it's really our problem.  And it doesn't crash on the 
machine I use.

I'm not saying it is, I just asked if it was a known problem. Now that
I know it isn't and nobody can reproduce it, I'll get around to debugging
it after I've installed gdb. Thanks.

I'm not sure the problem is worth bothering about if it never crashes except 
on itself.  Note that the testsuite does exercise 'strip' (albeit lightly).
