Bug report: acp55 segfault

John Fisher
Expert 1030 points

Here's cl55_segfault.c

------------


static const int a[1];

int
main(void)
{
    (void)a[0];

    return 0;
}

static const int a[1] = { 0 };
----------------

Here's a Command prompt session

    AartiG,

    I've taken a look at the report you have entered. Is there a way of tracing this report back to the information I supplied, and in particular the short source file I posted?

    Well, searching for SDSCM00042368 on this forum finds this thread, so the test case and SDSCM number are already known to be linked, but I assume that's not what you mean.

    Test cases in the SDSCM database are not published.  The TI support team will add a public description field describing the conditions of the bug, so that users can determine if they have the same bug, but the original source code is not revealed.
