I'm using DJGPP for few month now, and I'd like to congratulate 
the GNU and DJGPP team.

I have noticed a strange behaviour when calling exit() in a destructor
for static object. In this case, exit() *DOES NOT* exit :))))) 
I guess this is a bug. If it is not, then can someone explain me.

Here's a simple example, the program does nothing interesting but
shows what might be a bug :

// --- cut here ----------------------------------------------------
// exit() strange behaviour example
#include <assert.h>

class t_foo {
public:
   ~t_foo() { assert(0); }  // always false assertion, calls exit
};

t_foo foo;                  // static allocation

int main() {
   return 0;                // how can I do easier? :)))
}
// --- cut here ----------------------------------------------------

And here is the bug:
C:\gcc -o foo foo.cc -lgpp
C:\foo

Assertion failed at foo.cc line 5: 0
Exiting due to signal SIGABRT
Assertion failed at foo.cc line 5: 0
Exiting due to signal SIGABRT
Assertion failed at foo.cc line 5: 0
Exiting due to signal SIGABRT
Assertion failed at foo.cc line 5: 0

!!!ENDLESS EXIT MESSAGES!!!

Here's some info on my system and DJGPP compiler version:
C:\gcc --version
2.7.2

C:\>go32-v2
go32/v2 version 2.0 built Jan 23 1996 22:03:02
Usage: go32 coff-image [args]
Rename this to go32.exe only if you need a go32 that can run v2
binaries as
 well as v1 binaries (old makefiles).  Put ahead of the old go32 in
your PATH.
