6799,Assert hit in dl-close.c when calling dlclose on libboost_date_time.so,Christophe Dumez <christophe.dumez@…>,az_sw_dude,"I get the hit the following assert when calling dlclose() on libboost_date_time.so:
Inconsistency detected by ld.so: dl-close.c: 759: _dl_close: Assertion `map->l_init_called' failed!

I wrote a small test library and test app to reproduce the issue.
1. Compile libchild.so library. It is a library which links against libboost_date_time.so but has a missing symbol.
2. Compile test-dlopen.c and run the app.

The test-dlopen app will:
1. Call dlopen(""./libchild.so"", RTLD_NOW), which will fail because of the missing symbol (normal). It will probably recursively load libboost_date_time.so since libchild.so links against it.
2. Call mh = dlopen(""/usr/lib/libboost_date_time.so"", RTLD_NOW), which will succeed (normal).
3. Call dlclose(mh), which will hit the assert.

The output of the test app is:
$ ./test-dlopen 
trying to load ./libchild.so...
Failed to load: ./libchild.so: undefined symbol: _Z15registerMethodsv
trying to load /usr/lib/libboost_date_time.so...

I tried with:
boost v1.48 + glibc 2.13 (Tizen)
boost v1.47 + glic 2.14.90 (Fedora)
