Hi folks, When I run a console program from the console, I get a message saying This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. But it works fine when I run the program from gdb. Methinks the console interface isn't being set up right. The -mwindows, -mconsole, -mole options seem to have no effect. My linker command is presently gcc.exe -s -o jsdb_gcc.exe -mconsole -mwindows -mole obj\gcc\*.o obj\gcc\jsdb.coff -lole32 -lws2_32 -lstdc++ -lodbc32 -loleaut32 -lmapi32 -lcomdlg32 -luuid Any suggestions? Thanks! Shanti |

Methinks the console > interface isn't being set up right. This set of symptoms arises frequently. Typically, the problem is an uninitialized variable. Such a variable has a random value when you run it normally, but the debugger may happen to zero-initialize it, making the program seem to work. Try to reduce the program to a tiny testcase that reliably reproduces the problem. Once you've eliminated everything that's not the problem, you'll probably see it. Alternatively, try using a 'malloc debugger' such as mpatrol. Or add lots of runtime assertions to check sanity at every step. Or try using a map file to find where the problem is, and backtrack from there. |

heapcheck may be useful too (may need to modify it a bit to compile with mingw): http://www.softlab.ece.ntua.gr/~ttsiod/HeapCheck.html Also there's DrMingw (from mingw-utils), for JIT debugging , great for these situations. Also, make sure you use the latest stable mingw. Happy bug busting. :) Greg Chicares wrote: > Shanti Rao wrote: > >> >> When I run a console program from the console, I get a message saying >> >> This application has requested the Runtime to terminate it in an >> unusual way. >> Please contact the application's support team for more information. >> >> But it works fine when I run the program from gdb.

Thanks for the suggestions. The problem turned out to be that argv[0] wasn't I was expecting, and my attempt to fopen(argv[0]) failed.

This smells as if you've an invalid memory reference somewhere. Possibly an uninitialized pointer.
