Re: [gcmd-dev] Migration to C++

[Michael]

Let's see..

poll([{fd=6, events=POLLIN}, {fd=10, events=POLLIN|POLLPRI, revents=POLLIN}, 
{fd=11, events=POLLIN|POLLPRI}, {fd=12, events=POLLIN|POLLPRI}], 4, -1) = 1

It's polling widget events (regularly)

Here comes your click:

read(10, "GIOP\1\2\1\1f\0\0\0", 12)     = 12
read(10, "P\230\203\277\0\0\0\0\1\0\0\0\1\0\0\0\f\0\0\0\1\1\1\1\1"..., 102) = 
102
open("(null)", O_RDONLY|O_LARGEFILE)    = -1 ENOENT (No such file or directory)
open("(null)", O_RDONLY|O_LARGEFILE)    = -1 ENOENT (No such file or directory)

This is possibly the crash cause:

stat64("/home/magnus/slackware/slp_archive-0703292107.tar.bz2", 
{st_mode=S_IFREG|0644, st_size=3006361, ...}) = 0
--- SIGSEGV (Segmentation fault) @ 0 (0) ---


... good ol' segmentation fault. (What about the tar.bz2 file? You clicked on 
it by case ?)
Maybe we should have a close look at this function 'stat64' ? 
Apparently it's the 64bit 'stat'....what library is it ? libc6 (=glibc) ?

I think we need to be sure this was a typical log. 
Magnus, would some additional stracings always be looking the same (basically) ?

write(3, " \0\2\0\0\0\0\0", 8)          = 8
write(3, "%\0\1\0+\0\1\0", 8)           = 8

i think the rest is family talk (parent, child) to finally say goodbye.
