Re: [Lcms-user] Problems getting 1.08 to run on Redhat 7.2

[Jim M. <jm...@ro...>]

Oops... I lied... the actual fault is in TIFFClose(in).  A stack trace 
shows the following:

The immediate problem is with the (conditional on ICC_SUPPORT) field 
in.tif_dir.td_profileData.  The field contains accessible data before 
the call to TIFFClose, but the memory is apparently freed during a call 
to the routine LZWCleanup.
