           Summary: Valgrind errors can appear in output window only after
                    program exits
           Product: kdevelop
           Version: unspecified
          Platform: SuSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: valgrind integration
        AssignedTo: kdevelop-bugs kdevelop org
        ReportedBy: receive-spam yandex ru


Version:            (using KDE KDE 3.5.5)
Installed from:    SuSE RPMs
Compiler:          gcc 4.1.2 
OS:                Linux

Consider program like this:


#include <stdio.h>

int main(int argc, char *argv[])
{
    bool *b = new bool;
    if (*b)
        printf("Preved\n");
    while (1) ;
    return 0;
}


If we do Debug - Valgrind Memory Leak Check in KDevelop main menu for this program, \
we will only see "Memcheck, a memory error detector blah blah blah" in Valgrind \
output. Error message "Conditional jump or move depends on uninitialised value(s)" \
(which is written by valgrind when program reaches line "if (*b)") will be seen only \
after we terminate the program by choosing Build - Stop in main menu. The reason is \
that valgrind does not print separator ("==NNNNN==" without any message) after error \
message so KDevelop thinks message isn't finished. The easiest solution is to make \
valgrind write a separator after each error message (not before the next message like \
it does now, BTW extra separators don't seem to be a problem).

This problem does exist in the most recent SVN versions of KDevelop 3.4 and valgrind \
3.3.
