I'm not entirely sure *where* in the stack the issue is. I'm using Vala 0.7.7, and when I compile the libvfcgi project I am receiving a segfault at line 56 of http://is.gd/5mlyT -- however, a segfault there should not be possible, as I understand it. So, either I'm doing something horribly wrong that I cannot see, or there's something horribly wrong somewhere else that I cannot see. Can anyone perhaps tell me what I've done wrong?
The change that introduced the crash was the one wherein I initialized and created the new object: http://bazaar.launchpad.net/~mtrausch/libvfcgi/trunk/revision/21/libvfcgi/server.vala The thing I don't get is *why* that would crash at all. GDB says: Program received signal SIGSEGV, Segmentation fault. 0x00007ffff7bd73e6 in fast_cgi_server_construct (object_type=6330480, error=0x7fffffffe1a0) at server.c:208 208 self->priv->m_mainloop = (_tmp0_ = g_main_loop_new (NULL, FALSE), _g_main_loop_unref0 (self->priv->m_mainloop), _tmp0_); Of course the problem there is that there are multiple statements and I know not which one is actually crashing. Looking at the disassembly, I get: 000000000000d391 <fast_cgi_server_construct>: d391: 55 push %rbp d392: 48 89 e5 mov %rsp,%rbp d395: 41 54 push %r12 d397: 53 push %rbx d398: 48 81 ec b0 00 00 00 sub $0xb0,%rsp d39f: 48 89 bd 58 ff ff ff mov %rdi,-0xa8(%rbp) d3a6: 48 89 b5 50 ff ff ff mov %rsi,-0xb0(%rbp) d3ad: 48 c7 45 e8 00 00 00 movq $0x0,-0x18(%rbp) d3b4: 00 d3b5: bf 20 00 00 00 mov $0x20,%edi d3ba: e8 69 8d ff ff callq 6128 <g_mall...@plt> d3bf: 48 89 45 e0 mov %rax,-0x20(%rbp) d3c3: 48 8b 45 e0 mov -0x20(%rbp),%rax d3c7: 48 89 45 d8 mov %rax,-0x28(%rbp) d3cb: be 00 00 00 00 mov $0x0,%esi d3d0: bf 00 00 00 00 mov $0x0,%edi d3d5: e8 de 87 ff ff callq 5bb8 <g_main_loop_...@plt> d3da: 48 89 45 d0 mov %rax,-0x30(%rbp) d3de: 48 8b 45 b8 mov -0x48(%rbp),%rax d3e2: 48 8b 40 18 mov 0x18(%rax),%rax d3e6: 48 8b 00 mov (%rax),%rax 0xd3e6 is the line that is causing it to crash, according to the backtrace. I haven't the slightest how to follow it from there, so I am hoping that someone here can see my error or provide some insight as to what might be being done wrong. --- Mike _______________________________________________ Vala-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/vala-list
