Ensure we use value of FS at the time the record was read
benhoyt opened this issue · comments
I just read this comment in onetrueawk's lib.c
, and GoAWK (I think) doesn't do this and probably has this issue.
/*
* POSIX specifies that fields are supposed to be evaluated as if they were
* split using the value of FS at the time that the record's value ($0) was
* read.
*
* Since field-splitting is done lazily, we save the current value of FS
* whenever a new record is read in (implicitly or via getline), or when
* a new value is assigned to $0.

void savefs(void)
