------- Comment #4 from burnus at gcc dot gnu dot org 2008-01-19 20:49 ------- I can reproduce it on x86-64-linux. The first error valgrind shows is
==25404== Invalid read of size 8 ==25404== at 0x44361B: gfc_match_common (match.c:2756) ==25404== by 0x4522B9: match_word (parse.c:64) That line is: while (old_blank_common->common_next) The problem is essentially the same as for PR 33375: We have a half-deleted symbol somewhere. I believe the right spot is gfc_match_common; somewhere the error recovery does not properly delete a symbol or forgets a pointer = NULL. When trying to debug PR 33375 I never quite understood why it was failing. I had also the feeling that the patch in PR 33375 might not be fully right. My starting point would be gfc_match_common either with the current tree or with the patch of PR 33375 reverted. -- burnus at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Ever Confirmed|0 |1 GCC build triplet|i686-apple-darwin9 | GCC host triplet|i686-apple-darwin9 | GCC target triplet|i686-apple-darwin9 | Last reconfirmed|0000-00-00 00:00:00 |2008-01-19 20:49:48 date| | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34858
