From bug #16947:
on slackware-10.2, file-4.17's libmagic is deployed without *.mgc binary compiled databases and mldonkey at some point (not right away nor after some download) fail to load the plain version of /etc/file/magic

Your crash also happens while opening /etc/file/magic, you also
miss magic.mgc. These files are not provided by the Slackware
package, you could circumvent this error by compiling GNU file yourself.

Yes, thx.
I downloaded the cvs and used the disable magic flag.
runs fine now, thx :)

best regards,

It seems Slackware really has problems with its GNU file packages.
Current version of GNU file is 4.17.

To disable it in MLDonkey use --disable-magic, for more configure
options see ./configure --help

hello.

first of all i encountered the same problem as a bugreporter before with file, so i installed file 4.13 and copied the .mgc file to /etc/file (because mldonkey was looking here...).
i started mldonkey again, everything looks fine, but after some time the core crashed... here is what strace says:

open("/etc/file/magic", O_RDONLY|O_LARGEFILE) = 75
fstat64(75, {st_mode=S_IFREG|0644, st_size=43776, ...}) = 0
mmap2(NULL, 131072, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7cb8000
read(75, "\34\4\36\361\2\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 131072) = 43776
read(75, "", 131072) = 0
read(75, "", 131072) = 0
close(75) = 0
munmap(0xb7cb8000, 131072) = 0
open("/dev/tty", O_RDWR|O_NONBLOCK|O_NOCTTY) = 75
writev(75, [{"*** glibc detected *** ", 23}, {"free(): invalid next size (norma"..., 34}, {": 0x", 4}, {"085458b8", 8}, {" **\n", 5}], 5** glibc detected *** free(): invalid next size (normal): 0x085458b8 ***
) = 74
rt_sigprocmask(SIG_UNBLOCK, [ABRT], NULL, 8) = 0
tgkill(24288, 24288, SIGABRT) = 0
--- SIGABRT (Aborted) @ 0 (0) ---
+++ killed by SIGABRT +++
Process 24288 detached

[1]+ Done strace /3rd_party/bin/mlnet

i just downloaded the source, untar'd it, run ./configure, installed ocaml in the local dir and installed it with make install (prefix=/3rd_party).

i'm running slackware current with gcc 3.4.6, glibc 2.3.6, kernel 2.6.17. is it possible to disable the mime magic in the configure script? would be really nice if mldonkey would run... i dont think i need this feature, do i?

best regards,

oliver
