Last modified: 2012-06-18 02:20:40 EDT
From Bugzilla Helper: User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.2.19-7.0.1 i686) Description of problem: internal error segfault during compilation of various octave modules. Can resume make, compiles a number of modules OK, then segfaults again. How reproducible: Always Steps to Reproduce: 1./configure --enable-shared --enable-lite-kernel 2.make 3. Actual Results: part way thru build c++ reports internal error: segfault: c++ -c -fPIC -I. -I.. -I../liboctave -I../src -I../libcruft/misc -I../glob -I../glob -DHAVE_CONFIG_H -mieee-fp -fno-implicit-templates -g -O2 -Wall ./DLD-FUNCTIONS/quad.cc -o pic/quad.o ./DLD-FUNCTIONS/quad.cc: In function `octave_value_list show_quad_option (const string &)': ./DLD-FUNCTIONS/quad.cc:397: Internal error: Segmentation fault. Can resume build with 'make'. Picks up where it left off then later segfaults again on a different module. See attachment. Expected Results: no segfaults Additional info: 2.2.19-7.0.1 #1 Sat May 5 20:50:55 PDT 2001 i686 unknown [Athlon 256MB/256MB swap) gcc-2.96.69 glibc-2.2.12
Created attachment 20412 [details] make output (edited)
Make output is not useful. Can you add -save-temps -v options to gcc command lines which cause segfaults and attach here preprocessed sources it creates (files with .ii extension)? And if you have time, try a newer gcc (the one from RHL 7.1 or even better from rawhide) instead?
jakub -- please ignore this bug report for now. I've got hardware problems that may be causing this behavior (kernel oopses, spontaneous reboots --> CPU fan dead). I'll try again after things get fixed. At least I got updated gcc's out of it. Thanks. --peter
Please reopen the bug if you find something reproducible.
