Hi, I have a customer with a problem regarding ladebug. Every time he tries to debug a certain file he gets a core dump, when invoking ladebug. He is running Digital UNIX 4.0b and ladebug version 40-25. His object file was linked with C, C++ and fortran modules. Used the following compiler versions: f77 V3.8-064 cc V5.2-033 cxx V5.3-004 He sent me a stack trace of his core file: 0x1246209c ------------------ object file name: /aed405/home/AIS20/OSF1V3.2/runtime/exe/ais Reading symbolic information ...Assertion failed: alternateEntryPointStack != NULL src/libsrc/ladebug/parsesymscoff.C 9104 This is an unexpected condition and may indicate the presence of a defect. If you wish to report this, please include the stack trace that follows. Diagnostic stack trace ... 0x1246209c 0x1245fc04 0x1245ecf4 0x1243dc44 0x123d495c 0x124202e8 0x12395abc 0x12226350 0x122133cc 0x1220fd5c end of diagnostic stack trace. Ladebug Debugger Version 4.0-25 caught signal "IOT/Abort trap" (6). This is an unexpected condition and may indicate the presence of a defect. If you wish to report this, please include the stack trace that follows. Diagnostic stack trace ... 0x242f5a50 0x243a5650 0x2431db04 0x24367f44 0x2437ea6c 0x2426e074 0x2428a210 0x2428b624 0x2428b668 0x2426d64c 0x2426d788 0x123b0c5c 0x1246209c 0x1245fc04 0x1245ecf4 0x1243dc44 0x123d495c 0x124202e8 0x12395abc 0x12226350 0x122133cc 0x1220fd5c end of diagnostic stack trace. I have no clue what this could mean. Your help is greatly appreciated, Ludwig. CSC Munich [Posted by WWW Notes gateway]

Would you please have the customer try out ladebug 4.0-30? We have put in some fixes in this area since 4.0-25. Thanks Wanfang | |||||

Generally, this means that there is unsupported compiled code somewhere in the image. Versions of Fortran-77 prior to 3.6 did not correctly output alternate entry point information. This caused ladebug to produce this behavior. Please make sure that ALL fortran code, including all libraries that contain fortran code, are compiled with -g and with F77 3.6 or later. If the problem still persists, we will need to have the binary to reproduce the behavior. The sources may or may not be necessary, depending on what we find. Any chance there is assembler code in here some place? Regards, Tim | |||||
