Revision 976 - (show annotations) (download) (as text)
Tue Dec 19 13:52:51 2006 UTC (13 years, 1 month ago) by johnpye
File MIME type: text/x-python
File size: 8426 byte(s)
Improved line/file/func reporting via Asc_Panic, using CPP var-arg macros under GCC.
Added ASC_ASSERT_LT and ASC_ASSERT_EQ assertion macros.
Tracking down a crash in IDA (ongoing).
