Hello forum members,

I get different results if I run gcov on the command line (text file output) and as eclipse gcov plugin.

gcov command line text output file shows (correctly):

        -:  122:void
       41:  123:process( void )
        -:  124:{
       41:  125:    if ( state_updated == true )
        -:  126:    {
        -:  127:        uint8_t step;
        -:  128:
        4:  130:        step = data_shadow[STEP];
        -:  132:
        4:  133:        state_updated = false;
        -:  135:    }
       41:  136:}

eclipse gcov plugin shows (wrong):

            122:void
       41   123:process( void )
            124:{
       41   125:    if ( state_updated == true )
            126:    {
            127:        uint8_t step;
            128:
        4   130:        step = data_shadow[STEP];
            132:
        4   133:        state_updated = false;
            135:    }
        0   136:}

The last line of the eclipse gcov plugin output shows a coverage of '0' (red) instead of '41'. This effect is only visible on some functions. Always on the last line of this functions.

I'm using Eclipse Kepler SR1 CDT and GCov Plugin 1.1.0.201312100517 (mingw with gcc 4.8.1 on a windows 7 host).

Any help will be appreciated.

I experience the same problem. I believe this is a bug in the gcov plugin and should be reported.

In addition, sometimes lines are red that can't possibly be red, such as
