stream bug with "0xBlabla" strings in internal mode

[Samuel Krempp <krempp at cmla dot ens-cachan dot fr>]

The bug was reproduced with the following g++ :
gcc version 3.1 20010624 (experimental) - cvs
gcc version 3.1 20010707 (experimental) - cvs
gcc version 3.0 20010402 (Debian prerelease)
i686-pc-linux-gnu

and is not present in
gcc version 2.95.4 20010319 (Debian prerelease)

With the faulty compilers, the resulting string looks like :
Trap!ZZZÜø

(the 2 last chars vary, clearly comig from improper memory accesses)
