Taken from the configure script of groff, I found a bug in the elf
version of c++.
Here is the example:
#ifdef __cplusplus
extern "C" void exit(int);
#endif
extern "C" {
void _exit(int);
}
int i;
struct A {
char dummy;
A() { i = 1; }
~A() { if (i == 1) _exit(0); }
};
volatile A a;
int main() { return 1; }
Compile it with 'c++ -aout' and the exit value is 0.
Compile it just with 'c++' and the exit value is 1!
This leads to a bug in the groff package. Since the constructors
for some global class instances are not called, the default value
for font_path is not set and therefore groff fails to format any
man page.
Regards
Frank
