The strange combination of FreeBSD/i386, stable/10, OpenSSL from ports, optimized assembly code, Dell PowerEdge 1950, Intel Xeon X5450@3.00GHz, and BIOS 2.5.0, resulted in core dumps for all applications linked with OpenSSL from ports.

Update 2015-01-05: I was more or less forced to adopt VT, UTF-8, KMS, and DRM2 when I upgraded my laptop from stable/9 to stable/10 in the time between Christmas of 2014 and New Year of 2015.
