c++ - What does this memory map mean when I compile my program? -


i using ubuntu lucid lynx, use kate code c++ programs , use g++ compile them. writing genetic algorithm program , works fine except memory map 80% of time execute program. cannot figure out memory map means or how solve it. here output:

*** glibc detected *** ./main: double free or corruption (!prev): 0x0881fdc8 *** ======= backtrace: ========= [0x80da7f8] [0x80dec69] [0x80a5441] [0x80a546d] [0x8059227] [0x8058b2f] [0x8058f41] [0x80567ec] [0x80c075f] [0x8048191] ======= memory map: ======== 00149000-0014a000 r-xp 00000000 00:00 0          [vdso] 08048000-08165000 r-xp 00000000 08:02 2101716    /home/armandmaree/desktop/projek_fase2 (copy)/main 08166000-08168000 rw-p 0011d000 08:02 2101716    /home/armandmaree/desktop/projek_fase2 (copy)/main 08168000-08170000 rw-p 00000000 00:00 0  09a45000-09a67000 rw-p 00000000 00:00 0          [heap] b7600000-b7621000 rw-p 00000000 00:00 0  b7621000-b7700000 ---p 00000000 00:00 0  b77e2000-b77e3000 rw-p 00000000 00:00 0  bfc35000-bfc4a000 rw-p 00000000 00:00 0          [stack] aborted

if know how can figure out problem lies or @ least explain me memory map means, great. in advance.

the memory map telling process crashed. [backtrace:] part tells stack trace (which function called function) when crash happened. memory map telling data @ addresses in process.

like others suggested in comments, compile -g , run program under debugger (gdb) better information. since crash caused heap corruption, using valgrind tool because specializes in type of problem.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).

javascript - Clean way to programmatically use CSS transitions from JS? -

as title implies, there proper way set initial css properties (or class) , tell browser transition these value? for example ( fiddle ): var el = document.queryselector('div'), st = el.style; st.opacity = 0; st.transition = 'opacity 2s'; st.opacity = 1; this not animate opacity of element in chrome 29/firefox 23. because ( source ): [...] you’ll find if apply both sets of properties, 1 after other, browser tries optimize property changes, ignoring initial properties , preventing transition. behind scenes, browsers batch property changes before painting which, while speeding rendering, can have adverse affects. the solution force redraw between applying 2 sets of properties. simple method of doing accessing dom element’s offsetheight property [...] in fact, hack work in current chrome/firefox versions. updated code ( fiddle - click run after opening fiddle run animation again): var el = document.queryselector('div'...
