Hi List,
When trying to compress something with level "Z_NO_COMPRESSION",
Valgrind indicates that GZIP is trying to access an unitialized memory
in "deflate.c" :
==2727== Conditional jump or move depends on uninitialised value(s)
==2727== at 0x804BA85: fill_window (deflate.c:1325)
==2727== by 0x804BBBD: deflate_stored (deflate.c:1418)
==2727== by 0x804ACCF: deflate (deflate.c:791)
When using other compression levels (Z_DEFAULT_COMPRESSION,
Z_BEST_SPEED, Z_BEST_COMPRESSION), everything seems to be OK to Valgrind.
Please, find attached my "deflate.c" and "snippet.c".
Any advice ?
cheers
Younès
