>Description:
Hi !!!

What I am doing is 

$ gcc test.cpp
gcc: Internal compiler error: program cpp got fatal signal 11
$ gcc -v
Reading specs from /usr/local/lib/gcc-lib/i686-pc-linux-gnu/2.95.2/specs
gcc version 2.95.2 19991024 (release)

The actual file test.cpp is:

#define DEB(y,x...) fprintf(stderr, #x" = "#y"\n",x)
void main(void)
{
        int fromblock;
        DEB(toblock)
}

Well, I know that the problem is with wrong args. number to
the macro I define, however, SIGSEGV is a strange way to report 
errors, isn't it ??

WBR, Bohdan.

#define DEB(y,x...) fprintf(stderr, #x" = "#y"\n",x)

}
