[Bug c++/11648] New: gdb crashes with segmentation fault when printing larger objects

["sven dot anderson at snom dot com" <sourceware-bugzilla at sourceware dot org>]

System: Linux anderssv-lx-01 2.6.32-22-generic #33-Ubuntu SMP Wed Apr 28
13:27:30 UTC 2010 i686 GNU/Linux
Glibc: 2.11.1-0ubuntu7.1
g++: 4.4.3-4ubuntu5

The following happens only with gdb 7.1 and latest snapshot, 7.0.1 works fine.

Since my last system update to Ubuntu 10.4 I was unable to use the debugger for
our software project in eclipse. I noticed that gdb has been updated to 7.1 and
found out that I can reproduce a segmentation fault with a few steps by just
setting a breakpoint in main and from there printing a string object three times
(own implementation, not std::string) and quitting it with q each time. I will
attach a session log with glibc debugging informations and backtrace.

In eclipse it even crashes when I step through the code, but I don't know if
there are also prints involved while stepping in eclipse.

If you need any further information I will try to provide it.
