Description Chris 2015-06-06 20:12:44 UTC

=sys-block/gparted-0.22.0 segfaults when gcc 5.1.0 is installed. Gparted was compiled using gcc-4.9.2 (it won't compile with gcc 5.1.0). This is the output I get from gdb when I try to run it:

Starting program: /usr/sbin/gpartedbin 
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib64/libthread_db.so.1".

Program received signal SIGSEGV, Segmentation fault.
0x00007ffff594732a in std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >::_M_erase(unsigned long, unsigned long) ()
   from /usr/lib/gcc/x86_64-pc-linux-gnu/5.1.0/libstdc++.so.6

Also, it is impossible for me to downgrade - regardless if I switch gcc version.


Reproducible: Always

Steps to Reproduce:
1. run gparted
Actual Results:  
gparted segfaults

Expected Results:  
Gparted would run normally.

you must compile all c++11 programs with the same minor gcc version.

if some program does not compile with gcc 5.1, please open a new bug with emerge --info and build.log.
