[Octave-bug-tracker] [bug #56952] segfault during compilation while processing doc/interpreter/genpropdoc.m

[Dmitri A. Sergatskov]

Follow-up Comment #6, bug #56952 (project octave):

I have seen very similar crashed. More often recently. 
E.g. see all fedora buildbot crashes. 
I also got them on my workstation(s). 

After freashly built octave:


$ rm -rf doc/
$ make V=1 -j8
/bin/sh config.status oct-conf-post.h-tmp oct-conf-post.h
/bin/sh config.status liboctave/mk-version-h.sh-tmp liboctave/mk-version-h.sh
/bin/sh config.status libinterp/corefcn/mk-mxarray-h.sh-tmp
libinterp/corefcn/mk-mxarray-h.sh
/bin/sh config.status build-aux/subst-script-vals.sh-tmp
build-aux/subst-script-vals.sh
/usr/bin/mkdir -p doc/doxyhtml && \

/usr/bin/mkdir -p doc/interpreter && \

/usr/bin/mkdir -p doc/liboctave && \
: > doc/liboctave/.octave-dirstamp
/usr/bin/mkdir -p doc/refcard && \
: > doc/refcard/.octave-dirstamp
rm -f bits/stl_algo.h

Attached is the trace as captured by system logger.

I wonder is the "hgsave weirdness" as discussed on maint list
is somewhat related to this as well.

Dmitri.
