fatal: internal error: file profile.c, line 1232: unexpected opcode Op_lint_plus

[Hermann Peifer]

Hi again.

AFAICT: the fatal error only happens when profiling/pretty-printing in
combination with using --lint and having a "+" sign in the ternary
expression.

Regards, Hermann

# Fatal error with "1+1" in the ternary expression
> gawk -o- --lint 'BEGIN{1>2?1+1:2}'
BEGIN {
        gawk: cmd. line:1: fatal: internal error: file profile.c, line 1232:
unexpected opcode Op_lint_plus

# Works as expected with "1-1"
> gawk -o- --lint 'BEGIN{1>2?1-1:2}'
BEGIN {
        1 > 2 ? 1 - 1 : 2
}

# Works as expected without "--lint"
> gawk -o- 'BEGIN{1>2?1+1:2}'
BEGIN {
        1 > 2 ? 1 + 1 : 2
}
