Hey,
I know it's not that urgent and as a matter of fact only a theoretical
problem, but still..
g++ crashes for a very long function name ;)
consider this perl program to generate such a stupid-evil source file:
a.pl:
#v+
my $name = "a"x(1024*1024*8);
open( FD, "> test.cpp" ) or die "ohmygawd";
print FD <<EOF
#include <iostream>
void $name(){
std::cout << "cheers\\n";
}
int main( int argc, char** argv ) {
$name();
return 0;
}
EOF
;
print "Compiling..\n";
system "g++ -c test.cpp -o test -Wall -ansi";
#v-
outpus:
Compiling..
g++: Internal error: Segmentation fault (program cc1plus)
Please submit a full bug report.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.

On my system it crashes for 8*1024*1024 chars. I guess this number is
very depended on the actual pc configuration.

I know it's stupid but java for instance does not simply allow longer
names than 65535 (iirc).
