In Mac OSX ver. 10.3, I got following internal compiler error.

Confirmed, I only get the failures on powerpc-darwin and not on
x86_64-linux-gnu for some reason.

I've see this on amd64-*-freebsd.  A brief debug session
is described here.

I don't see this failure any more on powerpc-apple-darwin7.9.0. Can anyone
confirm it's still present? (perhaps Steve on amd64)

I believe that this bug still exists since the below testcase would be a
duplicated one.

       p = c(:,:)
       s = matmul(p,transpose(q)) - e

Well it works for me wth 20060507 so I am going to close this as fixed.

Neither your new code ice.f90 nor the transpose_char_1
testsuite code exhibits the ice on amd64-*-freebsd.
