[Lessfs-users] nullpointer segfault in lib_common.c (1.4.2)

[Märt B. <spa...@gm...>]

Hi!

I can't find the bugzilla and sourceforge won't let me send a message to
mruijter. So I'll file my bug report here.

lessfs-1.4.2 crashes on my gentoo box with segfault. My use flags are:
USE="crypt -debug -lzo -memtrace". The segfault is created in
lib_common.c line 1276:

if (0 != strcmp(config->blockdata_io_type, "file_io")) {

In my case, config->blockdata_io_type is null and the program crashes.
blockdata_io_type is usually set in lib_common.c:3116 (parseconfig),
except #ifndef HAMSTERDB. Possible fix could be adding the following
lines (maybe? is "tokyocabinet" correct?):

@3153
 #ifndef HAMSTERDB
+        config->blockdata_io_type = "tokyocabinet";
         config->blockdatabs = read_val("BLOCKDATA_BS");
         LINFO("The selected data store is tokyocabinet.");
 #else
