Follow-up Comment #73, bug #53733 (project octave):
Another observation: graphicsmagick plays quite nicely when it comes
to signal handling: it refrains from installing its own handler when
one is already installed. Or to be precise: because there is no
function to simply inquire about the existing handler, graphicsmagick
installs its own signal handler, checks whether there was a
non-default handler installed, and restores the old handler if there
was one. See the source at:
http://hg.code.sf.net/p/graphicsmagick/code/file/356b0eba718c/magick/magick.c#l633
In any case, gdb confirms that the initialisation of
ImageMagick does not modify the signal handler for SIGSEGV:
1) at octave start-up:
11 SIGSEGV Segmentation fault
octave::deadly_sig_handler(int) in section .text of
/home/adrian/Programmes/slurp/octave-2cf750f5cb7d/libinterp/.libs/liboctinterp.so.5
2) after executing 'javaaddpath (".");':
11 SIGSEGV Segmentation fault signalHandler(int,
siginfo_t*, void*) in section .text of
/usr/lib/jvm/java-10-openjdk-amd64/lib/server/libjvm.so
3) after executing 'fmt = imformats ();'
11 SIGSEGV Segmentation fault signalHandler(int,
siginfo_t*, void*) in section .text of
/usr/lib/jvm/java-10-openjdk-amd64/lib/server/libjvm.so
Does this mean that the SEGV signal *handling* is not the culprit in
this bug, despite java's shenanigans in throwing that signal for an
argument size of 10^5 elements (about equal to the stack size) ?
The series of instructions
javaaddpath (".")
fmt = imformats ();
graph = javaObject ("Baz");
graph.addNodes (1:1e4);
graph.addNodes (1:1e5);
produces a SIGSEGV at the last line, but executes fine if the second
line is omitted. The table of signal handlers however is exactly the
same in both cases (whether ImageMagick is initialised or not).
A detailled debugging session follows for the script above.
$> gdb -ex 'handle SIGSEGV nostop print pass' -ex 'source
Programmes/pas_de_moi/signals.gdb' --pid=${$(ps -C octave-gui -o pid=)// /}
