Package: gdb Version: 7.7.1+dfsg-3 Severity: normal Dear Maintainer,
when trying to debug a certain C++ executable, gdb crashes during startup. The last thing printed is "Reading symbols from exe...". After debugging gdb the problem seems to be in the c++ demangling functions of the contained libiberty. The backtrace of the crash contains a call to cplus_demangle() with a rather long mangled name (and options 3). Calling it with this name seems to trigger an endless recursion in d_print_comp(). I wrote a small test program to reproduce the problem. Calling the cplus_demangle() function from libiberty contained within the gdb source package caused a segfault. Linking the same test program against the lib shiped by the libiberty-dev package did not cause a segfault but produced the correct result. So an update of the libiberty contained in gdb seems to solve the problem. If it is required I can send you the name causing this problem in a private message, but I don't want to send it to a public list.
