It works by calling abort(), as intended.
If you take another look in functexcept.cc you'll see that when
__EXCEPTIONS is defined the following definition is used:
void
__throw_logic_error(const char* __s)
{ throw logic_error(_(__s)); }
This allows the library to call __throw_logic_error without caring
whether the target supports exceptions, or whether they have been
disabled with -fno-exceptions. If exceptions are enabled
__throw_logic_error will throw std::logic_error, otherwise it will
call abort().
It seems that the 68k amigaos port does not support exceptions, or
your GCC was configured without support for exceptions.
Hope that helps,

"__throw_logic_error" abort, but print no error message out
Hello
the file in bits/basic_string.tcc call it.
template
template
_CharT*
basic_string<_CharT, _Traits, _Alloc>::
_S_construct(_InIterator __beg, _InIterator __end, const _Alloc& __a,
forward_iterator_tag)
{
#ifndef _GLIBCXX_FULLY_DYNAMIC_STRING
if (__beg == __end && __a == _Alloc())
return _S_empty_rep()._M_refdata();
#endif // NB: Not required, but considered best practice.
if (__builtin_expect(__is_null_pointer(__beg) && __beg != __end, 0))
__throw_logic_error(__N("basic_string::_S_construct NULL not valid"));
<---
But in libstdc++v3/src/functexcept.cc
void
__throw_logic_error(const char*)
{ std::abort(); }
this call abort and there is no string print out, because abort get no
Parameter as far i see.
How can this work ?
When i add testcode
std::__throw_logic_error("error text\n");
then also NO text is print out but program is quit
I have a gcc4.3.2 68k amigaos build, maybe problem is here, but i dont
understand how this can work with the current source and what i must change
in the build, without change in gcc core Files.
Please help
bye Bernd
