I think I have some interesting testing result for you ;-) I compiled latest gdb in your branch on MSYS2 on Windows [1], with my additional modification to enable build-with-cxx. It compiles fine. However, when debugging a simple hello world program, I got error below: "This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information." when debugging a simple hello world program. " Steps to reproduce: 1. $ cat hello.c # include int main(void) { int a = 10; printf("haha a is %d\n", 10); return 0; } 2. compile with MSYS2 mingw gcc $ gcc hello.c -g -O0 -o hello.exe 3. debugging hello.exe with gdb (build with cxx) $ gdb hello.exe 3.1. set a breakpoint on main() 3.2. type `c` expect result: gdb should report that the program is not start yet. actual result: gdb exit with error message: "This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information." when debugging a simple hello world program. " Then I tried build gdb again without build-with-cxx, and this error disappear, gdb works as expect, at least for simple hello world.
