Bugs that only show on one system are quite common. That's one of the big
advantages in testing on multiple platforms. I have hit many such bugs
over the years.
* I recall writing some multi-threaded code which worked fine on numerous
systems - Linux, HP-UX, Unicos, Solaris, tru64 and IRIX. But it
occasionally failed on AIX. I suspected it was an AIX bug, but then I
realised it was a bug in my code, which could have shown up on any
operating system. It just never did.
* I recall an ex-colleague writing some finite difference code that
worked fine on hi Linux system, but crashed on a quad core Solaris
machine. He then looked at his code carefully and found there was a
genuine bug.
I actually find that there are some bugs related to Singular and Pari that
show up on 64-bit Solaris. I suspect they are genuine bugs and could cause
problems on other system, but just have not to date
