Description Philippe Quesnel 2012-08-12 21:31:09 CEST 
(Note that I don't have access to 4.7.x or 4.8.x on Ubuntu, this might not apply anymore ! sorry if it is the case)

gdc (Ubuntu/Linaro 4.6.3-1ubuntu1) 4.6.3
DMD32 D Compiler v2.059

GDC allows this:
(it will crash on execution)

void main() {
    string str = "allo";
    str.reverse;
    str.sort;
}

But dmd will catch the error at compile time:

dmd testStringReverse.d 
  testStringReverse.d(4): Error: can only reverse a mutable array
  testStringReverse.d(5): Error: can only sort a mutable array
Comment 1 Johannes Pfau 2012-08-21 19:21:37 CEST 
This correctly prints the error at compile time with
gdc commit 9bcc0b7159 (4.7 branch)
gcc 4.7.1 (on ARM / raspberry pi, shouldn't matter)
dmd frontend 2.059

Please reopen this bug if it still occurs for you with the latest version of gdc.

gdc hello.d -o hello
hello.d:5: Error: can only reverse a mutable array
hello.d:6: Error: can only sort a mutable array

I'll try it out to be sure when I can get my hands on the newest version
thx
