I tried following now:
Moved ~/.emelfm2
xhost +
env -i DISPLAY=':0.0' strace -o /tmp/emelfm ./emelfm2 -l -n -x
then tried to expand commands (any, also non-existing)--> crash
in idle state in /tmp/emelfm ther are ongoing gettimeofday messages,
tried to put q and <tab> in command-line these last lines appear:
write(2, "\n(emelfm2:26285): GLib-CRITICAL "..., 82) = 82
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++
I use gentoo-linux, gcc-3.3.6/3.4.5
Build platform: GTK+ 2.8.8 Linux 2.6.15-gentoo-r1/i686
windowmaker
Eterm
bash
I tried a remote debian-machine: a bit different behavior, emelfm hang
up or crashed, strace shows something like this (in case of trying to
expand grep):
access("/usr/bin/grep-changelog.emacs21", X_OK) = 0
stat64("/usr/bin/grep-changelog.emacs21", {st_mode=S_IFREG|0755,
st_size=6950, ...}) = 0 getdents64(8, /* 124 entries */, 4096) = 4072
getdents64(8, /* 125 entries */, 4096) = 4088
getdents64(8, /* 125 entries */, 4096) = 4088
getdents64(8, /* 125 entries */, 4096) = 4096
getdents64(8, /* 128 entries */, 4096) = 4072
getdents64(8, /* 126 entries */, 4096) = 4096
getdents64(8, /* 130 entries */, 4096) = 4096
getdents64(8, /* 122 entries */, 4096) = 4088
getdents64(8, /* 127 entries */, 4096) = 4080
getdents64(8, /* 79 entries */, 4096) = 2616
getdents64(8, /* 0 entries */, 4096) = 0
close(8) = 0
open("/bin", O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY) = 8
fstat64(8, {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
fcntl64(8, F_SETFD, FD_CLOEXEC) = 0
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++
note: my system (emelfm2 not) is compiled with -fomit-frame-pointer, I'm
not a programmer, but probably that's the reason why my strace-output is
barely usable
