Large string constant causes C# compiler crash

Gnik

I created a C# application with some large string constants and whenever I
try to build the solution the compiler crashes with no error message. On
further analysis the problem seems to occur when the string constant has
around 2100 character. I tried changing the constant declaration to a string
variable declaration and it works fine.

Any ideas?

The following code can be used to reproduce the error:

const string TEST =
"12345678901234 567890123456789 012345678901234 567890123456789 012345678901234 567890123456789 01234567890" +

As far as I am concerned, that shouldn't cause a crash -and indeed doesn't
on my machine. Maybe you should post the full code of your problem (perhaps
you have a physical memory problem on your machine?).

Not able to reproduce here. Compiles and executes fine.

The full code is simply that line of code pasted into the Main function of a
default console application. It was a simple test app to diagnose the issue.

I've tried the same thing on 2 different machines with the same results both
running Windows XP SP2, one with 256 Mb RAM and the other with 1 Gb RAM. I'm
on Visual Studio .NET 2003 (7.1.3088) and .NET Framework 1.1 SP1 (1.1.4322)

Not reproducable so there must be a difference, any non visible characters
embedded perhaps? Use a binary view to see that.

Not able to reproduce here. Compiles and executes fine.

Also, compiles & executes using Jeff Kay's "Snippet Compiler"

I've tried the same thing on 2 different machines with the same results both
running Windows XP SP2, one with 256 Mb RAM and the other with 1 Gb RAM. I'm
on Visual Studio .NET 2003 (7.1.3088) and .NET Framework 1.1 SP1 (1.1.4322)

OK, I had pasted the code outside of main, at the class level. Putting
it inside main produces the same result as you are reporting.

Having spent a bit of time with this there are several clear things.
1. Compiles ok when const is a class member.
2. Falls over when large string const is within Class member (have tried
methods and properties -static or not does not make a difference)
3. Length of const IS making a difference as to whether falls over or not.
4. Your statement IS VALID.

This seems to be a bug in visual studio since your project will compile with
the command line util csc.

Your solution is thus.. declare the constants as private class level members
rather than within the method calls. This is actually good practice too
since you would otherwise be re-initializing a brand new const upon every
method call wheras declaring them as class members they will be initialized
once only.

See end for code...

Mark.

P.S. Good problem find!

try to build the solution the compiler crashes with no error message. On
further analysis the problem seems to occur when the string constant has
around 2100 character. I tried changing the constant declaration to a
string
variable declaration and it works fine.

Any ideas?

The following code can be used to reproduce the error:

const string TEST =

Having spent a bit of time with this there are several clear things.
1. Compiles ok when const is a class member.
2. Falls over when large string const is within Class member (have tried
methods and properties -static or not does not make a difference)
3. Length of const IS making a difference as to whether falls over or not.
4. Your statement IS VALID.

This seems to be a bug in visual studio since your project will compile
with the command line util csc.

On the plus side, it appears that its fixed in whidbey, atleast for up to
three times the length of the repo case.

Can I modify a constant variable through a pointer obtained from const_cast?

by: CoolPint | last post by:

While I was reading about const_cast, I got curious and wanted to know if I could modify a constant variable through a pointer which has been "const_cast"ed. Since the pointer would be pointing to the constant variable and if I changed the value through the pointer, the constant variable should have been modified. Well, that's what I thought until I wrote the following and run it. #include <iostream> using std::cout; using std::endl;
