Re: [fluid-dev] glib crash

[address@hidden]

Hello,

trying to build a debug version of glib, and will do some tests on the failing target machines.

In the meantime, I wanted to note that when I compile fluidsynth against the latest glib (v2.36.3), I get a lot a deprecation warnings related to mutex and threads :

/Users/antoine/Documents/Code/fluidXtra/src/fluidsynth-1.1.5/src/utils/fluid_sys.h:161:31: 'g_thread_init' is deprecated

/Users/antoine/Documents/Code/fluidXtra/src/fluidsynth-1.1.5/src/utils/fluid_sys.h:162:10: 'g_mutex_new' is deprecated

/Users/antoine/Documents/Code/fluidXtra/src/fluidsynth-1.1.5/src/midi/fluid_midi_router.c:150:3: 'g_static_mutex_free' is deprecated

etc..

Looking at the glib header files, I see this, in deprecated/gthread.h

GLIB_DEPRECATED_IN_2_32

void     g_thread_init                   (gpointer vtable);

Could this mean that the current glib, when being called with these deprecated functions, fails on some old systems ?

Thank you

Probably my fault for the multiple email post (got stuck in the admin
interface trap due to its size and I approved it without realizing
that it had made it to the list already somehow).

Anyways..

I had a look at the thread_memory_from_self() function in the glib
source code and I don't see anything that would suggest usage of SSE
instructions (its a memory allocation function).  There is a lot of
use of the thread system though, so that could be the culprit.  If you
have a problem system you can test with, I would try building Glib
with debugging information to see if you can get the actual source
code line that is causing the crash.  You could also do a disassembly
dump at the instruction pointer EIP, to see what the actual
instruction is, which also might provide some insight.  Either the
instruction was intended, but not supported on the problem system -
which would mean glib may have been built for a platform that was too
specific, or some sort of corruption is occurring.  Looking at how
glib got built (its build time options, thread support system, etc)
might also be useful information.

Hope that helps.

Best regards,

Element Green
