Ok, I send you the full log (compressed)
There are several entries that are probably real bugs (but harmless?)
related to
==14288== Use of uninitialised value of size 8

I guess we output uninitialized variables in the LYXERR call. Did you
run with any -dbg flag?
This is probably the problem:
==14288== Invalid read of size 1

==14288== by 0xA434BD: lyx::Messages::get(std::string const&) const
(in /usr/local/lyx1.6/bin/lyx)
The relevant function is:
bool setEnv(string const & name, string const & value)
{
// CHECK Look at and fix this.
// f.ex. what about error checking?
string const encoded = to_local8bit(from_utf8(value));
#if defined (HAVE_SETENV)
return ::setenv(name.c_str(), encoded.c_str(), 1) == 0;
#elif defined (HAVE_PUTENV)
static map<string, string> varmap;
varmap[name] = name + '=' + encoded;
return ::putenv(const_cast<char*>(varmap[name].c_str())) == 0;
#else
#error No environment-setting function has been defined.
#endif
return false;
}
Does somebody see why there is a memory allocation in the putenv case?
