Mark, Attached is a patch to components/synedit/synregexpr.pas that fixes alignment issues. I've tested the code against a test unit (attached) that is a mix of fpc/packages/regexpr/examples/testreg1.pp and Demos/SelfTest/TestRegExpr.drp (from the official TRegExpr package). The result is the same for aligned and non-aligned platforms (error 120,121,122,123,124 and 703). This tests only that my changes have not introduced a new bug, but, since I'm testing on Solaris x86, I can't be sure that all data is aligned properly. It's possible I've missed something. I've tried to set the AC cpu flag to force alignment checking but that generates alignment errors in libc :( Could you please test this on one of your sparc/arm systems? Thanks, Ludo
