107
<P>A bug exists, at least in the Macintosh version, where FunnelWeb V3.2
108
hangs when fed the following file:
113
@O@<X@>@{@<Y@>@}
114
@$@<Y@>@M@{@<Z@>@(@<Y@>@)@}
115
@$@<Z@>@(@1@)@{@1@}
119
<P>FunnelWeb has always (since V1 in 1986) had macro
120
recursion detection, but it appears to fail in this case.
121
You can workaround this bug by eliminating all recursive
127
<P>A bug exists in the output line length monitoring of
128
FunnelWeb V3.2. If you set the pragma <SAMP>indentation
129
= none</SAMP>, FunnelWeb still counts the output line lengths
130
as if they are being indented, even though they aren't.
131
You can workaround this by ignoring the output file line
132
length errors or by setting:
136
@p maximum_output_line_length = infinity
139
<P>The following source code patch has been proposed, but
144
In tangle.c, the code:
146
/* Output an EOL with indentation if desired. */
153
should be changed to:
155
/* Output an EOL with indentation if desired. */
157
{ eolblank(ind_base); ind_curr=ind_base; }
159
{ wf_chr(&f_o,EOL); ind_curr=0; }
