Public bug reported:
While updating the seq record reference documentation, we noticed that
if one tries to use a seq record in "Specified" mode, the LNK0 will
never be processed, regardless of the OFFS field.
Possible cause in src/std/rec/seqRecord.c:
if (prec->selm == seqSELM_Specified) {
int grpn = prec->seln + prec->offs;
if (grpn < 0 || grpn >= NUM_LINKS) {
recGblSetSevr(prec, SOFT_ALARM, INVALID_ALARM);
return asyncFinish(prec);
}
if (grpn == 0)
return asyncFinish(prec);
lmask = 1 << grpn;
}
(code from branch 3.15)
