If no, then no, since we already did a long interactive debug session without results (you said you didn't learn much however) (it is in the log on one of the days).	Anonymissimus <anonymissimus>

Fri 15 Feb 2013 11:34:25 PM UTC, comment #3: I'm posting a portion of the valgrind log, which looks relatively valid and did only show up with the -03 cmake release build, not with an scons debug build, but is over my horizon. This also caused wesnoth to crash (see the assertion failure at the end). I launched the thing with valgrind --suppressions=utils/valgrind_memcheck_suppressions.supp ./wesnoth_cmake_release_debug -d -t --config-dir=/media/HDI3_SOURCE_NTFS/wesnoth/userdata/ 1>val_log.txt 2>val_err.txt where wesnoth_cmake_release_debug was build with cmake -DCXX_FLAGS_USER="-ggdb3 -O3" trunk@r56322 I don't know whether it is actually related to this report.

Mon 11 Feb 2013 04:04:02 PM UTC, comment #2: The mentioned date is just the most important one, it is correct. The discussion was on at least 2 days. The thing I wanted me or someone else to do here is valgrinding such a build. I'd volunteer to do it if you tell me how to build with cmake/Linux with both debug info and -O3 (supposedly the key condition), which is probably a oneliner for you. I no longer have the hardware setup under which I (sometimes) "reproduced" this and don't expect something to come out of it, nor did I notice it recently, but also didn't try to trigger it.

Sun 10 Feb 2013 10:18:27 AM UTC, comment #1: Does the problem still exist? (Note the irclogs are from the 7th of April, not the 8th.)	Mark de Wever <mordante>
Sat 07 Apr 2012 10:34:12 PM UTC, original submission: reproduce: launch ./wesnoth -d -t Should segfault at the end of the "loading phase". Attached file gdb.txt contains the error message, backtrace with debugging info and disassembler output. Bug seems "very hard to reproduce"; I get this only sometimes and it seems only with the MinGw binary and only with the release built (which I added the option to have debugging info to). Other build options are (the last three are defines): [21:49] anonymissimus mordante: -O3 -Wall -mthreads [21:49] anonymissimus -march=native [21:49] anonymissimus -fexceptions [21:49] anonymissimus -fdiagnostics-show-option [21:49] anonymissimus -fopenmp [21:49] anonymissimus -Wno-strict-aliasing [21:49] anonymissimus -Wno-missing-braces [21:49] anonymissimus HAVE_PYTHON [21:49] anonymissimus USE_GZIP [21:49] anonymissimus _WIN32_WINDOWS compiler: g++ (tdm-1) 4.5.2 I couldn't yet reproduce this with MSVC or with the normal debug build (which has no -O whatever). IRC talk related to this is on #wesnoth-dev 08.04.2012, ~18 - ~22 o'clock.	Anonymissimus <anonymissimus>
