What we have as a doc is directly in the docstring of `comp-libgccjit-reproducer', I guess we could improve it. Essentially having it bound to t while compiling produces a C file deposed where the .eln target directory. This file ELNFILENAME_libgccjit_repro.c can be just compiled linking against libgccjit to obtain the reproducer. libgccjit should never segfault so if this crashes is clearly a bug. Andrea
