#3874: GHC.Exts.traceEvent segfaults
-------------------------------+--------------------------------------------
Reporter: cjs | Owner:
Type: bug | Status: new
Priority: normal | Component: Runtime System
Version: 6.12.1 | Keywords: event, eventlog
Os: Linux | Testcase:
Architecture: x86_64 (amd64) | Failure: None/Unknown
-------------------------------+--------------------------------------------
Comment(by cjs):
Oh, and for further fun, I've walked through the calls from traceMessage
down, and I don't see anywhere where we check for format specifiers in the
string the user passes in. I think we want to change this function:
{{{
void postUserMsg(Capability *cap, char *msg)
{
postLogMsg(&capEventBuf[cap->no], EVENT_USER_MSG, msg, NULL);
}
}}}
to have the body
{{{
postLogMsg(&capEventBuf[cap->no], EVENT_USER_MSG, "%s", msg, NULL);
}}}
