Traceback
When a Fortran program terminates due to a severe error condition, the Fortran runtime system displays additional diagnostic information after the runtime message.
The Fortran runtime system attempts to walk back up the call chain and produce a report of the calling sequence leading to the error as part of the default diagnostic message report. This is known as traceback. The minimum information displayed includes:
The standard Fortran runtime Runtime Message Display and Format text that explains the error condition.
A tabular report that contains one line per call stack frame. This information includes at least the image name and a hexadecimal PC in that image.
The information displayed under the Routine, Line, and Source columns depends on whether your program was compiled with the traceback option.
For example, if the traceback option is specified, the displayed information might resemble the following:
forrtl: severe (24): end-of-file during read, unit 10, file E:\USERS\xxx.dat Image PC Routine Line Source libifcorert.dll 1000A3B2 Unknown Unknown Unknown libifcorert.dll 1000A184 Unknown Unknown Unknown libifcorert.dll 10009324 Unknown Unknown Unknown libifcorert.dll 10009596 Unknown Unknown Unknown libifcorert.dll 10024193 Unknown Unknown Unknown teof.exe 004011A9 AGAIN 21 teof.for teof.exe 004010DD GO 15 teof.for teof.exe 004010A7 WE 11 teof.for teof.exe 00401071 HERE 7 teof.for teof.exe 00401035 TEOF 3 teof.for teof.exe 004013D9 Unknown Unknown Unknown teof.exe 004012DF Unknown Unknown Unknown KERNEL32.dll 77F1B304 Unknown Unknown Unknown
If the same program is not compiled with the traceback option:
The Routine name, Line number, and Source file columns would be reported as "Unknown."
A link map file is usually needed to locate the cause of the error.
The traceback option provides program counter (PC) to source file line correlation information to appear in the displayed error message information, which simplifies the task of locating the cause of severe runtime errors.
For Fortran objects generated with the traceback option, the compiler generates additional information used by the Fortran runtime system to automatically correlate PC values to the routine name in which they occur, Fortran source file, and line number in the source file. This information is displayed in the runtime error diagnostic report.
Automatic PC correlation is only supported for Fortran code. For non-Fortran code, only the hexadecimal PC locations are reported.
