[Octave-bug-tracker] [bug #30685] Segmentation fault in ./run-octave [sigemptyset() in liboctinterp-3.3.52.so]

[Leonardo Muttoni]

Follow-up Comment #16, bug #30685 (project octave):

After cleaning the building tree, I've changed my enviromental variables:

> export CFLAGS="$CFLAGS -g"; export CXXFLAGS=$CFLAGS

Wich turned these variables to "-march=nocona -O3 -g".

Then, I "./configure --prefix=/usr", "make -j3", and run "./run-octave -g":


> ./run-octave -g
(gdb) run

I'm a beginner in debugging. Please tell me any additional GDB commands that
I must run.

After build:

> ls libgnu/.libs/s*
libgnu/.libs/save-cwd.o  libgnu/.libs/sockets.o  libgnu/.libs/strftime.o 
libgnu/.libs/stripslash.o  libgnu/.libs/strnlen1.o

There is no "sigprocmask.o" here.

Another broader try:

> find -iname "sigprocmask*"
./libgnu/.deps/sigprocmask.Plo
./libgnu/sigprocmask.c

What is the next step?
