Yes, there are a couple of rather nefarious bugs in PK36. One of them has to do with PK[X]ARC snatching DOS interrupt vectors and not returning them to their previous values (INT 3 in particular is affected). Apparently Phil Katz installed this "feature" to prevent casual disassembling of his code. However, the vectors were not restored after the program exited. Details of this bug (and others) are available from SIMTEL20 under the <MSDOS.ARC-LBR> directory (where the MS-DOS archivers are stored). I am willing to e-mail or post the document files if anybody is interested. The bugs are real, though - they were independently documented by BBS sysops in Georgia and California. Most people have been switching back to PKX35A35 until they get the fixed copy of PK36.
