I am using the  D compiler on Mac OS X 10.4 ("gdc-0.24-mac-10.4.dmg" from
The following code crashes my gdc:

long atol (string str)
    extern (C) long atoll(char *nptr);
    return atoll(cast(char *)(str));

When running gdc, it says:

crash.d: In function ‘atol’:
crash.d:5: internal compiler error: Bus error
Please submit a full bug report ...

If I put the "extern (C)" declaration out of the function, the bus error goes

            Version|2.004                       |1.020

As an issue tracker newbie, I first got the "Component" & "Version" fields
wrong. Meantime, I corrected the "Version" to 1.020 following the output of the
"gdc -v" command:

Using built-in specs.
Target: powerpc-apple-darwin8
Configured with: /usr/local/staging/r24rc1/gcc-5363/build/obj/src/configure

Thread model: posix
gcc version 4.0.1 (Apple Computer, Inc. build 5363) (gdc 0.24, using dmd 1.020)

Also, I gained the impression that the actual failing component is the gcc
backend, not gdc itself. Nevertheless, the builders of gdc / dmd will be far
better capable than myself of determining the cause of the crash...
