Created attachment 83 [details]
Example file. When compiling this, cc1d locks up.

By accident I forgot to add a '&' in front of Reset_Handler in this array:

Steps to reproduce:
Build the attachd file 'start.d'.

Results: cc1d locks up.

build: f378f9a, branch=gdc-4.9


Code:
VectorFunc [3] g_pfnVectors = [
    &Reset_Handler, /* If removing the '&' here, cc1d locks up. */
    ];

Speculation: This bug might relate to all platforms or perhaps a Big Endian
issue if it's not reproducible on for instance X86.

Note: Unfortunately, the tools that Apple provide for debugging locks up, when
I'm trying to sample the process, in order to find out where it locks up.
