This could be a "Well, don't do that then" situation. I tried your
testcase, but I compiled it using "g++ t.cpp" and got a working executable
with no sign of an abort:

It's always best to use the proper language driver for compiling C++ instead
of adding -lstdc++ to the C compiler command-line, in fact it's not a
supported mode of operation and in upcoming versions of the compiler will be
non-conformant because it'll break the libstdc++ malloc wrappers. Please let
us know if using the g++ driver fixes the problem for you.
