Bug #: 39
Summary: gdmd segfault during compilation of simple matrix
multiplication routine
Classification: Unclassified
Product: GDC
Version: 4.7.x
Platform: x86_64
OS/Version: Linux
Status: NEW
Severity: critical
Priority: Normal
Component: gdc
AssignedTo: ibuc...@gdcproject.org
ReportedBy: j.e.a...@gmail.com

source code that induces gdmd to segfault
See the attached source file for a simple matrix multiplication test. When
attempting to compile on linux with gdmd, the compiler segfaults. The gdc
compiler should complain if it doesn't like the code, but it should never
itself segfault.
