+Subject: [PATCH] Fix crash in lexer refill (reported by Agostino Sarubbo).
+
+The crash happened in a rare case of a very long lexeme that doen't fit
+into the buffer, forcing buffer reallocation.
+
+The crash was caused by an incorrect calculation of the shift offset
+(it was smaller than necessary). As a consequence, the data from buffer
+start and up to the beginning of the current lexeme was not discarded
+(as it should have been), resulting in less free space for new data than
+expected.
