I compile the following test.cpp with this command: > g++8 -o test test.cpp -L/usr/local/lib -lxerces-c The resulting executable test crashes: > $ ./test > Segmentation fault File test.cpp: > #include <iostream> > int main(int argc, char **argv) { } Removing -lxerces-c or removing #include <iostream> eliminates the crash. The crash is in static constructors. libxerces-c.so is from xerces-c3-3.2.0_2 11.2-STABLE
This is some kind of libc++ conflict not fixed by USES=fortran.
