The default case in OpenSSL is to use SSE2 instructions in the x86 assembler code. However, SSE2 instructions utilize the x86 XMM registers, which are not saved and restored in setjmp/longjmp, nor are they stored and restored in signal handling under Cygwin. In the long run Cygwin should save and restore the XMM registers on x86 as well, I guess. For the time being, I've build a new OpenSSL version 1.0.1f-2 with the "no-sse2" flag. With this version I could clone the linx repo without error. Please give it a try.
