+Subject: [PATCH] go/scanner: reject large line and column numbers in //line
+ directives
+
+Setting a large line or column number using a //line directive can cause
+integer overflow even in small source files.
+
+Limit line and column numbers in //line directives to 2^30-1, which
+is small enough to avoid int32 overflow on all reasonbly-sized files.
+
+For #59180
