Package: libgccjit-8-dev Version: 8.3.0-6 Severity: normal Dear Maintainer,
Short: the libgccjit example from the GNU GCC tutorial on JIT segfaults. I tried to compile Emacs from GIT HEAD (aa354dd55b213b86ee8e3aa0365a6ad915838458), but during ./configure --with-native-compilation it spit out this text: ... checking for library containing inflateEnd... -lz checking for dladdr... yes checking for dlfunc... no checking for gcc_jit_context_acquire in -lgccjit... yes checking libgccjit.h usability... yes checking libgccjit.h presence... yes checking for libgccjit.h... yes configure: error: Installed libgccjit has failed passing the smoke test. You can verify it yourself compiling: <https://gcc.gnu.org/onlinedocs/jit/intro/tutorial01.html>. Please report the issue to your distribution if libgccjit was installed through that. Here instructions on how to compile and install libgccjit from source: <https://gcc.gnu.org/wiki/JIT>. I then tried the tutorial01.html example as well, and the compilation step of that page worked so far. But running it gave me this error: $ ./tut01-hello-world Segmentation fault While I wrote this error report, I also install libgccjit-8-dbg via apt-get and used GDB. The following backtrace happens: $ gdb ./tut01-hello-world Reading symbols from ./tut01-hello-world...(no debugging symbols found)...done.
