842566 - EXC_BAD_ACCESS (SIGSEGV) after building with DMD

Status: NEW

(Core :: DMD, defect)

Description

[Virgil Dicu [:virgil] [QA]]

Added this line to the mozconfig file before building e8f8a3f6f1f6 (latest from mozilla-central):

ac_add_options --enable-dmd

DMD initializes successfully, then Nightly crashes with this error: 

Exception Type:  EXC_BAD_ACCESS (SIGSEGV)
Exception Codes: KERN_INVALID_ADDRESS at 0x00000000ffffffd8

I can't reproduce this on OS X 10.7.5.
