Issue #2372 has been reported by John Marino. ---------------------------------------- Bug #2372: segfault correct detection failure http://bugs.dragonflybsd.org/issues/2372
Author: John Marino Status: New Priority: Normal Assignee: Category: Target version: The package devel/libsigsegv fails its final diagnostic test on DragonFly. For information, this does pass on FreeBSD 9. To repeat: > cd /usr/pkgsrc/devel/libsigsegv > bmake > cd ${WRKOBJDIR}/devel/libsigsegv/work/libsigsegv-2.10/ > gmake check The output of the fifth test (out of five) should be: | Starting recursion pass 1. | Stack overflow 1 caught. | Starting recursion pass 2. | Stack overflow 2 caught. | Segmentation violation correctly detected. | Segmentation violation correctly detected. | Test passed. | PASS: stackoverflow2 The actual output is: | Starting recursion pass 1. | Stack overflow 1 caught. | Starting recursion pass 2. | Stack overflow 2 caught. | Segmentation violation misdetected as stack overflow. | Test passed. | FAIL: stackoverflow2 The code of the test is here: http://fossies.org/dox/libsigsegv-2.10/stackoverflow2_8c_source.html What seems to be happening is that when the stack is exhausted, accessing an illegal memory location triggers the stack overflow handler before the sigsegv handler. I think it's a DragonFly bug. -- You have received this notification because you have either subscribed to it, or are involved in it.
