Hi,
I am using g_slice_new to alloc some memory in my work, and it seems that sometimes same
address would be returned if g_slice_new in different threads are called at the same time, I'm
wondering if anyone has ever encountered this problem? or it's already a known bug? because
i am using the glib2-2.12.3, it's really a bit old now.
i write a test program to create three threads to keep alloc and free mems using g_slice_new and
g_slice_free respectively, i will put the allocated mem in a hash table, so everytime after calls to
g_slice_new, i check if it's in the hash table , and it turns out that it does happen. and if i set
G_SLICE=always_malloc before i run the test program, there will be no problem. any advice will
be appreciated.
Attached is my test program, i copy some codes from ghash.c so that it can be compiled only with
gcc -o gslice_test gslice_test.c -lglib-2.0 -I/usr/include/glib-2.0/ -I/usr/lib64/glib-2.0/include/ -pthread
-g
Here is my enviroment:
