I get this with the tutorial (just the first thing I tried)

> Key: THRIFT-3273
> URL: https://issues.apache.org/jira/browse/THRIFT-3273
> Project: Thrift
> Issue Type: Bug
> Components: C glib - Compiler
> Affects Versions: 0.9.3
> Environment: Fedora 22 (gcc 5.1.1) on x86_64
> Reporter: Simon South
> Assignee: Simon South
> Priority: Minor
> Labels: c_glib, compiler
>
> 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.
