Simon South updated THRIFT-3273:
--------------------------------
Description:
In code generated by the compiler for C (GLib), a service's processor class
incorrectly treats function and void pointers as interchangeable: When adding
to the {{process_map}} hash table it supplies a pointer to a function, while
{{g_hash_table_insert}} expects a {{gpointer}} (effectively {{void *}}) to a
data object.
ISO C explicitly forbids this conversion as it is not compatible with all
architectures, and with its {{-pedantic}} option enabled gcc will generate
warnings like
{code}
gen-c_glib/calculator.c: In function 'calculator_processor_init':
gen-c_glib/calculator.c:1231:24: warning: ISO C forbids passing argument 3 of
'g_hash_table_insert' between function pointer and 'void *' [-Wpedantic]
calculator_processor_process_ping);
{code}
The compiler needs to be fixed so the code it generates does not try to use
function pointers where data (void) pointers are expected.
