[ Reported to the Debian BTS as report #188527.
Please CC [EMAIL PROTECTED] on replies.
Log of report can be found at http://bugs.debian.org/188527 ]
Regression from 2.95, rechecked with 3.0.4, 3.2 20030415, 3.3
20030415, HEAD 20030329.
the following program compiles (compiled as "g++ stackcorrupt.cpp"),
but crashes when run. It seems that the stack gets corrupted with that
variable-length array when A class with a virtual function is used
and the length assigning variable(foo) is being changed.
stackcorrupt.cpp:
--snip--
class A {
public:
virtual ~A() {}
};
int main(void) {
int foo=1;
A bar[foo];
foo++;
return 0;
}
--snip--
The same problem can also be reproduced by using the compiler from the
gcc-snapshot (20030314-1) or with the g++-3.0 (3.0.4-13). The g++-2.95
(2.95.4-17) does not have the same problem.
