[ccache] build octave with ccache causes segfault when checkinstall

[Kim Sun]

Dear maintainers,

if I try to build the latest octave development source with ccache and
afterwards checkinstall, the process fails on checkinstall. The whole
procedure:

apt-get install git mercurial autoconf automake flex bison gperf gnuplot
libreadline5-dev libncurses5-dev zlib1g-dev libatlas-base-dev fftw3-dev
libglpk-dev libsuitesparse-dev libarpack2-dev libhdf5-mpich-dev
libpcre3-dev libcurl4-gnutls-dev libqhull-dev gfortran libfltk1.1-dev
libgraphicsmagick++1-dev transfig epstool libhdf5-serial-dev
libfontconfig1-dev texlive


export CXX="ccache g++"

export CC="ccache gcc"

This looks like ccache causes a segfault. I have reproduced this on

different machines over the last 4 months.



If I run checkinstall without ccache it completes without error.



So my big questions are:

Am I doing something wrong in building octave?

Do you have the same problems when using ccache and checkinstall.

Should I fill a bug report against ccache (my guess) or checkinstall?
