mondo fails with fatal error...

[mread]

mondo v2.2.4-1.fc5 See: ​http://sourceforge.net/mailarchive/forum.php?thread_name=evhkfd%24u19%241%40sea.gmane.org&forum_name=mondo-devel

From that thread:

Errors: 9/4/07 * glibc detected * /usr/sbin/mondoarchive: realloc(): invalid next size: 0xb68141b8 *

Well, that's a fatal error :-)

And later: Could you download the tar.gz package and recompile mondo using -g. Then Launch it preceded by valgrind or use gdb (Cf: http://trac.mondorescue.org/wiki/TroubleShooting#CreatingBacktraces)

Further information required: Please provide explanation of "recompile mondo using -g"

[mread]

configure > make > make install

Now that you have a compiled verison ith -g could you launch either valgrind before your commen or use gdb as described on the wiki and provide back the info around the problem please ? TIA.

Oops, forgot the important stuff:)

(See attachment numbered 1) 1st ran mondoarchive with gdb from src/mondoarchive (mondo/mondoarchive didn't seem to exist), then again to make sure. Each time the process hung (gdb or mondoarchive?) and I needed to Ctrl-c to move on.

2nd ran mondoarchive with valgrind from src/mondoarchive - weird thing, valgrind/mondoarchive seemed to succeed! But, nothing was written to media (/mnt/cifs) - strange?

(See attachment numbered 2) 3rd ran mondoarchive with valgrind from home directory (ie using installed mondoarchive at /usr/local/sbin/mondoarchive) to see if there were any differences between what had been failing and what now seemed to sort-of succeed. This time valgrind/mondoarchive again seemed to succeed and backup was written to media at /mnt/cifs/morgansmachineDIFF-1.iso (haven't verified independently).

So 4th ran mondoarchive with gdb from home directory to see if it might succeed - but, it hung again. Just to make sure I left if for 4 Hrs before coming back and ending it with Ctrl-c again. Seemed to hang just the same as before with gdb.

Attached also are logs.

Thanks.

[Bruno Cornec]

Most of the problems reported here should be fixed in rev [1552]

Especially, in order to test if the problem seen is fixed, could you take the mondo/src/common/mr_string.c file and used the one of this rev, instead of the one you have and relaunch the same tests. That should fix the fatal error.

If you want to then test further, please also do the same with mondo/src/common/libmondo-archive.c and mondo/src/common/libmondo-filelist.c

[Bruno Cornec]

You may want to test with the current beta of 2.2.5 which is on the ftp server.

[Bruno Cornec]

Should be fixed with official 2.2.5. If not, please reopen the bug report.
