893 – The profile flag no longer seems to work on Linux x86 64

The -profile flag no longer works for me. I am compiling under 64 bit linux on a dual core machine (the binaries are 32 bit of course). This is broken on 1.0 and 1.003 at least.
If I look at it in gdb, I see this as the crash point.

Just for completeness:

import std.stdio;
int main(char[][] x)
{
 writefln("hello.");
 return 0;
}
$ dmd -ofhello hello.d
$ ./hello
hello.
$ dmd -ofhello hello.d -profile
$ ./hello
Segmentation fault

I could reproduce this on a Turion64 X2 (x86_64 dual core), running completely in 32 Bit mode.
Interestingly the segfault occures in main (not _Dmain) when you have just an empty main function:
$ cat proftst.d 
void main() {
}
$ dmd ./proftst.d
gcc proftst.o -o proftst -m32 -lphobos -lpthread -lm 
$ ./proftst
$
$ dmd -profile ./proftst.d
gcc proftst.o -o proftst -m32 -lphobos -lpthread -lm
$ ./proftst
Segmentation fault
$
With GDB:
Program received signal SIGSEGV, Segmentation fault.
