Package: libgcc1 Version: 1:4.7.2-5 Severity: normal Control: affects -1 gdb Dear Maintainer, GDB (since version 7.5) could take advantage of SystemTap probes in libgcc/libstc++ to allow "next" and the like to work properly when exceptions are thrown, even without the debugging symbols installed. All you have to do is add systemtap-sdt-dev to your Build-Depends, now that it's Architecture: all again.
