Hi, ECL from git does not build on Linux/AMD64 with gengc (it builds fine without). The symptom is a segfault in ecl_min Program received signal SIGSEGV, Segmentation fault. 0x000000000045ac05 in ecl_array_allocself (x=x at entry=0x993990) at /usr/local/src/ecl/src/c/array.d:545 545 return; -- Eric Marsden
