Description pelo 2012-01-27 03:41:27 UTC 
Using the latest built dmd/phobos/druntime code from git I get a compiler core dump:

Core was generated by `dmd -I../.. -g -debug -od../.obj -of../.obj/variant common.d variant.d ../teg/s'.
Program terminated with signal 11, Segmentation fault.
#0  0x00000000004f7a2f in TemplateMixin::hasPointers() ()
(gdb) bt
#0  0x00000000004f7a2f in TemplateMixin::hasPointers() ()
#1  0x000000000050cc0e in ClassDeclaration::toObjFile(int) ()
#2  0x00000000004a024f in Module::genobjfile(int) ()
#3  0x0000000000403c4f in main ()

I'm trying to build a minimal test case. dmd 2.047 has other compilation segfaults affecting my code, I'm a little worried I'll never be able to build my code with any D compiler above 2.046 again ;)

I really wonder why members is NULL.
