Please report this bug on the gcc bugzilla system here:

  https://gcc.gnu.org/bugzilla/enter_bug.cgi?product=gcc

The bug is in the name demangling functions supplied by
the libiberty library, which is [art of gcc, not the binutils.

Re: c++filt stack overflow bug

2018-09-17 Thread Nick Clifton
Hi Peng,

Thank you for telling us about this bug.

I did try to reproduce the bug using the latest version of the 
binutils development sources, but the problem did not occur.
Possibly you are using an older set of sources, or you are
running the test on a machine with a limited amount of stack
space.

Either way, please could you check the problem, and if it
still exists, report it here:

  https://gcc.gnu.org/bugzilla/enter_bug.cgi?product=gcc

This is actually the gcc bug reporting system, since the C++
demangling feature of the xc__filt program is actually supplied
by the libiberty library, which is maintained as part of gcc
rather than binutils.

Cheers
  Nick

Thanks. I will try a build using -Wl,-t to see if I can get more details about
the issue.

I meant two builds done using the same linker version (the same binutils
commit), as it is expected that different binutils versions could produce
different outputs. When we are doing two Tor Browser builds using a binutils
commit before 13e570f80cbfb2, we get the same output in both builds. When we do
two Tor Browser builds using 13e570f80cbfb2 or a later binutils commit, we get
a different output in the two builds (although we used the same binutils commit
in both builds).

Hi wcventure,

  Thank you for reporting this bug.  Unfortunately you have reported it
  to the wrong project.  The demangler is part of the libiberty library
  which is maintained by the gcc project, not the binutils project.  So
  please could you refile this bug report here:

https://gcc.gnu.org/bugzilla/enter_bug.cgi?product=gcc

  Thanks.

Cheers
  Nick

Hi wcventure,

  Thank you for reporting this bug.

  The libiberty library, which includes the cplus_demangle_type function
  is actually part of the gcc project, rather than the binutils project.
  (The binutils use the library, but we do not maintain it).  Therefore,
  please could you refile this bug report here:

https://gcc.gnu.org/bugzilla/enter_bug.cgi?product=gcc

  Thank you.

Cheers
