files that can be used to reproduce the crash
Problem description:
Program received signal SIGSEGV, Segmentation fault.
std::basic_string<char, std::char_traits<char>, std::allocator<char>
>::basic_string (this=0x7fffffffb478, __str=
<error reading variable: Cannot access memory at address 0x29>)
at
/usr/src/debug/gcc-4.7.2/obj-x86_64-tizen-linux/x86_64-tizen-linux/libstdc++-v3/include/bits/basic_string.tcc:175
A number of files that can be used to reproduce the crash can be found in the
attached crash_files.zip archive.
The files were generated by fuzzing valid files, in order to check for problems
when libreoffice handles malformed input.
The bug was found while testing Libreoffice version 4.0.1.2, but it is
persistent in version 4.1.2.3
Steps to reproduce:
1. Open libreoffice with gdb attached
2. Open the files from crash_files.zip
A gdb backtrace example of opening one of the files can be found here:
