I am trying to run valgrind on a multithreaded websockets based program, to
check for memory leaks. Valgrind crashes in the middle of the program with
following errors:
--17214-- REDIR: 0x6e44620 (libc.so.6:__memcpy_chk) redirected to 0x4a28770
(_vgnU_ifunc_wrapper)
--17214-- REDIR: 0x6e7c2a0 (libc.so.6:__memcpy_chk_avx_unaligned)
redirected to 0x4c34e10 (__memcpy_chk)
valgrind: m_translate.c:1772 (vgPlain_translate): Assertion 'tres.status ==
VexTransOK' failed.

I have tried changing the operating system (from fedora to mint and
ubuntu). I also checked out the latest valgrind valgrind --version
valgrind-3.13.0.SVN to see if that will help me alleviate the issue. It did
not help. Can someone please advise how to get around this issue.
