WARNINGS<br />

BUGS<br />

When sdb prints the value of an external variable for which there<br />

is no debugging information, a warning is printed before the value.<br />

The value is assumed to be int (integer).<br />

Data which are stored in text sections are indistinguishable from<br />

functions.<br />

Line number information in optimized functions is unreliable, and<br />

some information may be missing.<br />

If a procedure is called when the program is not stopped at a<br />

breakpoint (such as when a core image is being debugged), all<br />

variables are initialized before the procedure is started. This<br />

makes it impossible to use a procedure which formats data from a<br />

core image.<br />

When setting a breakpoint at a procedure, sdb will inconsistently<br />

produce the incorrect line number. This seems to occur when the<br />

object file is newer than the source file. Recompiling the source<br />

program will correct this problem.<br />
