Right. g_malloc, g_free, malloc, and free are regularly mixed
in the code. I'll give a couple notable examples.
src/modules/module_utils.c defines a function named module_strip_ssml.
It returns a pointer to memory allocated with libc's malloc.
In src/modules/ibmtts.c, that memory is freed with g_free,
while in src/modules/flite.c, it is freed with libc's free.
src/c/api/libspeechd.c defines a function named
spd_send_data_wo_mutex. This function can return either malloc'ed or
g_malloc'ed data, depending on the condition of an if statement.
Its caller has no way of knowing whether the memory was allocated by libc
