Comment:
Keith, thank you for your work on porting libgccjit to MinGW.
I have now quite successfully used this to build the latest version of the
"native-comp" branch of GNU Emacs using mingw.org's MinGW tools.
However, there seems to be a fly in the ointment: Emacs built with the library
sometimes (rarely) crashes when calling libgccjit functions. It crashes in
strange ways: the C stack seems to be smashed when it does (GDB is unable to
show a backtrace), and stepping through the Emacs code which involves libgccjit
calls affects which of the libgccjit calls crashes(!).
So I need to put some serious debugging into this, but the fact that
libgccjit-0.dll is stripped of all debug symbols gets in the way. Would it be
possible for you to make the DLL with the debug symbols available for download?
Also, the GCC source distribution on the MinGW site seems to be before applying
all the MinGW patches: at least the libgccjit patches seem to be not applied.
is that intentional?

Ticket details:
ease add libgccjit to the binaries included in the MinGW GCC distributions.
This is required to be able to build projects that use libgccjit for JIT
compilation of code.
One example of this is "gccemacs", a branch of GNU Emacs development (soon to
land
on the master branch of Emacs) that compiles Emacs Lisp programs into native
x86 code
for faster runtime performance.
Thank you.
