Comment(by wgmitchener):
I've been working with gtk 2.32.4, ghc 7.4.2, and the development tree
from gtk2hs. I added a few print statements and tracked down this much of
the problem:
{{{
makeCallback: funPtr = 0xb7e8900c
makeCallback: destroyFunPtr = 0x0821fcd6
g_timeout_add_full: function = 0xb7e8900c
g_timeout_add_full: data = 0xb7e8900c
g_timeout_add_full: notify = 0x821fcd6
g_main_dispatch: dispatch = 0xb7ed11c0
g_main_dispatch: source = 0x82c0500
g_main_dispatch: callback = 0xb7e8900c
g_main_dispatch: user_data = 0xb7e8900c
g_timeout_dispatch: source = 0x82c0500
g_timeout_dispatch: callback = 0xb7e8900c
g_timeout_dispatch: user_data = 0xb7e8900c
(gdb) disass /r 0xb7e8900c,+5
Dump of assembler code from 0xb7e8900c to 0xb7e89011:
0xb7e8900c: e8 c3 14 3b 50 call 0x823a4d4
End of assembler dump.
(gdb) disass /r 0x823a4d4,+20
