Bug#581202: libpcre3 8.02-1 causes approx/stable to segfault

When I build approx 3.3.0 from source in stable, and then use sid's libpcre3, I get a segfault as well. Actually, the segfault can be reproduced very easily by compiling an empty file test.ml with the following command: ocamlc -I +pcre pcre.cma -linkall test.ml and then running ./a.out. So I guess anything using OCaml pcre3 bindings will have the same issue. I am still narrowing down the bug...

Is this the only reason why this bug is RC and pcre3 hasn't migrated to testing? Cheers, -- Stéphane -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of unsubscribe.

Is this the only reason why this bug is RC and pcre3 hasn't migrated to testing? Well, the segfault is likely caused by a change in pcre3 that broke ABI compatibility somehow. Don't you think that it is clearly RC ? -- | Lucas Nussbaum | lu...@lucas-nussbaum.net http://www.lucas-nussbaum.net/ | | jabber: lu...@nussbaum.fr GPG: 1024D/023B3F4F | -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of unsubscribe.

It works OK on i386. The version in unstable works on both. Although I can reproduce this easily, I'm not sure how to go about tracking down the problem. There are no debugging symbols in the released binary so gdb doesn't reveal much. When I built approx 3.3.0 from source, it worked (or at least didn't crash on startup, I didn't try to install it). pcre_config(0, 0x7fffd014, 57, 0x7f7e6fb36900, 0x7fffcf40) = 0 pcre_config(1, 0x7fffd014, -84616, 0x7f7e6fb36900, 0x7fffcf40) = 0 pcre_config(2, 0x7fffd014, -84632, 0x7f7e6fb36900, 0x7fffcf40) = 0 pcre_config(4, 0x7fffd014, -84584, 0x7f7e6fb36900, 0x7fffcf40) = 0 Which returned OK, so it didn't crash in these functions. I'm not sure what ltrace outputs if a signal is received during a library call, does it output anything for the library call at all? i.e. could there be another pcre function called after these ones, which ltrace hasn't output anything for because of the seg fault? -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of unsubscribe.
