Hi,
It looks like
if (staticData.ThreadCount() != 1)
{
UserMessage::Add("IRST LM not-threadsafe");
return false;
}
is being triggered so m_lmtb = NULL then a method of NULL is being
called in the destructor.
LanguageModelIRST::~LanguageModelIRST()
{
#ifndef WIN32
TRACE_ERR( "reset mmap\n");
m_lmtb->reset_mmap();
#endif
delete m_lmtb;
}
I added "if (m_lmtb)" and checked this in. The real question is why did
it think it has multiple threads if your configuration did not specify
multiple threads? Might try a git pull then a clean compile with
./bjam -j8 link=shared --prefix=/tools --with-irstlm=/tools
--with-giza=/tools/giza-pp/bin --install-scripts=/tools/scripts -a
