It is likely that GDC is from the D1 era.

If one is D1 and the other is current D, it is possible.

Of courne not intentional like that but clearly there is some incompatibility there.

I don't know for sure but neither GDC nor LDC packages that come under Linux distributions are modern enough.

If so, I would remove GDC and try installing only dmd 2.063 again.

Tried that in all sorts of combinations. Still no use.

Would there be some config files conflicting? But such conflicts would be reflected at compile time, not runtime, right?

Since I don't want to reinstall my Ubuntu system just for this (that would be so Windows-like!), I'd appreciate pointers to resolve the situation. Thanks.

Or should I take this to the d.gnu list or something?

Sometimes running ldconfig will solve wierd problems like this.

Thanks and I tried that just now but no fruit. :-(

Not that package,  it's an old D2 release, circa 2.046. and even then it has a different library name (libgphobos.a) and the module headers are installed in a separate directory from dmd.

Try a *full* removal of the deb installations (dmd and gdc).

apt-get purge <program_name>

Then reinstall latest DMD first. and test before moving on with GDC.

If you are installing GDC from the distro, it's likely to be very old and of questionable use.

I would not trust the DEB package as my understanding is that the deb are not being properly produced at this time. Like I said, try a full removal using "purge" and reinstalling again.

If you can attach your test-case program that segfaults compiled on that Kubuntu x86_64 I would be grateful.

It will allow to see if it is OS problem, hardware problem or it is DMD that is producing bad code in some specific scenarios.

Also it is easier to debug and reverse program when binary is given.
Thanks in advance.
