[Tracker] Random crashes in tracker-miner-fs from trunk

[Laurent Aguerreche <laurent aguerreche free fr>]

Hi!

I am trying Tracker from the trunk (always with the latest version) and
I am experiencing random crashes with ontologies:

Program received signal SIGSEGV, Segmentation fault.

    at tracker-ontology.c:168
168             return g_memdup (namespaces->data, sizeof (TrackerNamespace *) *
(namespaces->len + 1));

By the way, I run tracker this way :
$ cd dir_libexec
$ gdb ./tracker-miner-fs
run -p


I think that tracker-miner-fs will be launched automatically in the
future by "something".



Plus, I cannot build tracker-sparql-builder.vala because the following
lines are not translated correctly in C:

[CCode (cname = "strcspn", cheader_filename = "string.h")]
extern static size_t strcspn (string s1, string s2);

they produce the following declaration in tracker-sparql-builder.c:
gsize strcspn (const char* s1, const char* s2);


So, I get these errors when I build the C file:
tracker-sparql-builder.c:69: error: expected identifier or â(â before
â__extension__â
tracker-sparql-builder.c:69: error: expected identifier or â(â before
â)â token

I have to comment this declaration in order to build the C source,
moreover it is unneeded since this function is declared in string.h.


Rgds,
Laurent.
