unresolved external symbol _d_throwc

[Chris via digitalmars-d-ldc]

Hello

I downloaded LDC 17b1 to try and compile my little program with 
gtkd, under windows, 64 bits.

I compiled Gtkd 3.2.1 with this version of LDC and all went fine. 
Then I compiled my program and all went fine. However when it 
comes to linking I get these messages:

gtkdgl.lib(GLConfig_42_2e9.obj) : error LNK2019: unresolved 
external symbol _d_throwc referenced in function (mangled name) 
(glgdk.GLConfig.GLConfig 
glgdk.GLConfig.GLConfig.__ctor(gtkglc.glgdktypes.GdkGLConfigMode, 
gtkglc.glgdktypes.GdkGLConfigMode))
gtkdgl.lib(GLContext_43_378.obj) : error LNK2001: unresolved 
external symbol _d_throwc
gtkdgl.lib(GLWindow_71_30b.obj) : error LNK2001: unresolved 
external symbol _d_throwc

Searching for _d_throwc didn't yield any help, any ideas on how I 
could fix this?

FWIW, DMD2 works fine.

Thanks in advance.
