I had compiled with this line in the script launching it all:
export CPPFLAGS="$CPPFLAGS -DFOR_MSW=1 -I ${HERE_DIR}/libXpm-3.5.8/include -I ${HERE_DIR}/libXpm-3.5.8/src -L ${HERE_DIR}/libXpm-3.5.8/src"
I will recompile with it modified as follows (-Og added):
export CPPFLAGS="$CPPFLAGS -Og -DFOR_MSW=1 -I ${HERE_DIR}/libXpm-3.5.8/include -I ${HERE_DIR}/libXpm-3.5.8/src -L ${HERE_DIR}/libXpm-3.5.8/src"
Could you please confirm it is what you want before I go there.
Vincent.
PS: BTW, it won't be the same Emacs source code as the one crashing
anyway, because I did some git pull meanwhile. what shall I do with
that, shouldn't I try another git pull to work on the latest src
version, or should I try to get the same src as the one crashing by
getting a work area revision bashed on crashing Eamcs version
compilation date.
