[Octave-bug-tracker] [bug #36161] segfault when using octave_map with g++ --std=c++11

[John W. Eaton]

Follow-up Comment #6, bug #36161 (project octave):

I also can't reproduce this problem with GCC 4.6.2 on a Debian system.  There,
valgrind gives me the following:


coredump:800> g++ --std=c++0x foo.cc -o foo
