[Valgrind-users] valgrind 2.1.1: "input in flex scanner failed"

[Thomas L. <tho...@jr...>]

Hi
I just updated to valgrind 2.1.1 (previous running version was 2.0) and 
I encounter a problem (I have never seen it with 2.0).
My C program uses a flex/bison parser for reading an input file. 
Valgrind exits while this input file is read, but without signaling any 
error.
What is really strange to me, is that my program actually parses this 
input files and prints outputs prooving it does. However, valgrind 
reports that the "input" in flex scanner failed.

I uses valgrind --tool=memcheck -v myprogram

Can anybody help in finding why valgrind is detached and reports such an 
error?
Thanks
Thomas

[many output from my program, reading the input file.]
