Package: grass
Severity: important
Please split macro LOC_CHECK_VERSION from aclocal
into LOC_CHECK_VERSION_STRING and LOC_CHECK_VERSION_NUMBER
and use them appropriate in configure.in.
Current version check is unreliable.
Generated snippet, i.e.:
#include "confdefs.h"
#include <stdio.h>
#include <proj_api.h>
int main(void) {
FILE *fp = fopen("conftestdata","w");
char *p;
p = PJ_VERSION;
fputs(p, fp);
return 0;
}
is compiled OK, only with "warning: assignment makes pointer from integer
without a cast".
When the created binary is executed, random (given by arbitrary version
integer) memory is accessed and result might be either segfault or garbage from
memory.
It currently segfault on GNU/Linux => package can be compiled
and returns garbage on GNU/FreeBSD => it FTBFS there.
It would be nice if you could get fixed it into upstream.
Temporarily the attached patch can be also used.
Thanks in advance,
Petr
