So Jan's backtrace is suspect. I don't know if that = could result from optimization, but I'll build a non-optimized glib and = see if I can get a more reliable backtrace. >=20 It is suspect, the error message does belong to g_private_set (frame = #2). Frame #1 should have been g_thread_abort. If there is indeed a = memory corruption, such as a stack overwrite, that might explain it. Or = it might just be that gdb is in error. The build BTW, was un-optimized. Jan D.
