Bug #2372
closed
segfault correct detection failure
Description
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.

We no longer use pkgsrc but in dports we got:
