I have a tif with zip decoding and after upgrading from 3.9.4 to 4.0.3
I have a problem.
On Linux 64bit the Libtiff handles the file correct but it show many message like this.
ZIPSetupDecode: (null).
ZIPSetupDecode: (null).
ZIPSetupDecode: (null).
On Solaris it crashing when trying to display the first error message. signal SEGV (no mapping at the fault address) in strlen at 0xfee32330
0xfee32330: strlen+0x0050: ld [%o2], %o1

The problem is that in the routine ZIPSetupDecode the function 'inflateInit' return -2 (Z_STREAM)
and sp->stream.msg is NULL
if (inflateInit(&sp->stream) != Z_OK) {
TIFFErrorExt(tif->tif_clientdata, module, "%s",
sp->stream.msg);
return (0);
The workaround seems to do:
if (inflateInit(&sp->stream) != Z_OK) {
if ( sp->stream.msg != NULL )
TIFFErrorExt(tif->tif_clientdata,
module,
"%s", sp->stream.msg);
return (0);
Any suggesstion what the best solution is?
