Comment 23 for bug 453931

On my win7 pro 64-bit, this reliably happens on every launch. The error occurs while inkscape starts, I never see the application window. I tried both the stable 0.48 and the very latest bleeding edge build inkscape_R9983-1012261236.

In the bleeding edge build, I tried gdb and see the following:

I also ran DEPENDS.EXE over it, and used its profile mechanism to log all DLL loads. Most of that log is the routine of loading the large number of referenced DLLS, but at the end it shows:

Entrypoint reached. All implicit modules have been loaded.
LoadLibraryA("gdi32.dll") called from "c:\windows\syswow64\USP10.DLL" at address 0x75A96890.

From this, it seems like PThreads is implicated, but I haven't had a chance to pursue it further.
