Only the version which uses g++-4 (lcd_cxx) will run on any of my
installations. The others segfault. If I relink, using gcc version
4.4.0 20090227, the .o files from gcc-4 run OK. So I think the problem
is in one of the libraries or collect2 associated with gcc-4. I have
built many copies of gcc-4 and gcc-5, and the only one this year which
didn't exhibit this problem was the 0227 build.
Why does the crtbegin.o which gcc-4 links say it was built from
cygming-crtbegin.c ?
