[Pkg-lyx-devel] Bug#820398: Lyx crashes with SIGILL on processors without cmov

[Johann Klammer]

Package: lyx
Version: 2.1.4-2

I got this while trying to build ngspice on my fileserver
(it holds the debian installation here, 
and ngspice dropped from testing)

dh_testdir
#cd build/manual && lyx --export ps manual.lyx.
cd build/manual && lyx --export pdf2 manual.lyx.
/home/klammerj/projects/dc_dc/ngspice-26/build/manual
/bin/sh: line 1:  1742 Illegal instruction     lyx --export pdf2 manual.lyx
debian/rules:78: recipe for target 'build-indep' failed
make: *** [build-indep] Error 132
make: *** Waiting for unfinished jobs....

trying to run the thing in gdb yields:
