the issue with duplicate names of debugging symbols #139

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
The "23_containers/bitset/input/1.cc" test case produces the following
linker errors if the debugging information is enabled (i.e. "-g" option is
used):

/tmp/ccNf4mZo.o:1.cc:(.lo.b._Z+0x0): multiple definition of `__eof'

/tmp/ccNf4mZo.o:1.cc:(.lo.b._Z+0x0): first defined here

/tmp/ccNf4mZo.o:1.cc:(.lo.b._Z+0x0): multiple definition of `__eof'

/tmp/ccNf4mZo.o:1.cc:(.lo.b._Z+0x0): first defined here

collect2: ld returned 1 exit status

The problem is in multiple definition of the "__eof" debugging symbol:

.def    __eof;  .val
_ZZStrsIcSt11char_traitsIcELm5EERSt13basic_istreamIT_T0_ES6_RSt6bitsetIXT1_EEE5_
_eof;
.scl    2;  .type   04; .endef

...

.def    __eof;  .val
_ZZStrsIcSt11char_traitsIcELm0EERSt13basic_istreamIT_T0_ES6_RSt6bitsetIXT1_EEE5_
_eof;
.scl    2;  .type   04; .endef

disable debugging for C++ and remove all related hacks for release: SDB 
debugging
format just can't cope.
