I'm having the same issue.

I would say rebuild druntime with debugging symbols so you can get the line where it crashes... but I guess building the library yourself will resolve the issue (as things have a habit of usually doing).

I've built an special 64-bit dmd v2.060 deb package. It includes dmd, druntime and phobos compiled with "-g -g3" flags for gcc and cc, and "-gc" flag for dmd.
Other binaries and 32-bit phobos library was removed.

I guess I should try this on Debian Unstable to catch extra data to see what is wrong with thread handling in 2.060 compared to 2.059 on Debian?

I already narrowed down the line (see my other replies): https://github.com/D-Programming-Language/druntime/blob/master/src/gc/gc.d#L103

The ClassInfo object resulting from GC.classinfo contains bogus data (or something). It seems to fetch the right object, but ci.init.length is 0 and ci.init.ptr is null.
