GMT

Test case:
#include <gmt.h>

int main() {
void* gmtapi;
struct GMT_OPTION* opt;
int ret;

gmtapi=GMT_Create_Session("test",2,GMT_SESSION_NOEXIT,0);
 if(0==gmtapi) return 1;

opt=GMT_Make_Option(gmtapi,'W',"");
 opt=GMT_Append_Option(gmtapi,GMT_Make_Option(gmtapi,'J',"M10c"),opt);
 opt=GMT_Append_Option(gmtapi,GMT_Make_Option(gmtapi,'R',"130/150/40/60r"),opt);
 ret=GMT_Call_Module(gmtapi,"mapproject",GMT_MODULE_OPT,opt);
 printf("%i\n",ret);
 GMT_Destroy_Session(gmtapi);
 return ret;
}

Output is:
mapproject: Internal Error = GMT_MAP_BAD_LAT_MIN
mapproject (GMT_mapproject): North is outside -90 to +90 degree range
0 0
0

The program itself returns correct error code:
gmt mapproject -JM10c -R130/150/40/60r -W; echo $?
mapproject: Internal Error = GMT_MAP_BAD_LAT_MIN
mapproject (GMT_mapproject): North is outside -90 to +90 degree range
1
