Hi,

I compiled and linker a program -debug and the linker crashed.
If I use -release flag , then the linker does not crash but then the program
crashes.
The program uses CTFE which may have to do with the crash.

The program uses a large compile-time generated function which seems to contribute to the problem.

The picture doesn't help at all. You need to provide a source file which will reproduce the error.

Created an attachment (id=516)
one file that causes the problem

this if compiled as

dmd.exe -g compilerfailuretest.d

will produce the error.
Note download this file
too:http://www.dsource.org/projects/scregexp/browser/trunk/scregexp.d
That file is needed to place it in the same directory where
compilerfailuretest.d is located.

Thanks, I can reproduce the bug now.

it is possible to influence the occurance of the error by
reducing the size of
the statement ...auto perlreg = new
screg!("/(?:(?<tok>\\#(?:.*?(?:"~eol~")|.*\\z))|
(?<tok>\"(?:(?>\\\\\\\\|\\\\\"|.))*?\")|

when parameter is smaller, the error does not occur.

Somewhat reduced test case.

This cuts it down to a single, self-contained file. (Funny -- I recognize my own code in there -- almost all the comments are mine!) There's plenty of work still to be done in cutting in right down.

Completely reduced test case shows it's due to nested functions.
----------
char[] foo(int n) {
  if (n == 0)  return "void xxxx() {}";
  return "void xxxx() { void yyyy() { }" ~ foo(n-1) ~ "}";
}

mixin (foo(400));

Even smaller test case. Seems it happens with a depth around 512; it's probably exceeding the maximum symbol length.
---
char[] foo(int n) {
  return "void abcde() {" ~ ( n>0 ? foo(n-1): "") ~ "}";
}

mixin (foo(500));
