    <p><code>EXC_BAD_ACCESS</code> doesn't generate an exception so you first function doesn't work with the case. It generates a signal <code>SIGSEGV</code> or <code>SIGBUS</code>.</p> <p>Please refer to <a href="http://cocoawithlove.com/2010/05/handling-unhandled-exceptions-and.html" rel="noreferrer">Handling unhandled exceptions and signals</a> by Cocoa with Love.</p> <p><strong>Update</strong></p> <p>I just checked the source code of LLDB. It might be <code>TARGET_EXC_BAD_ACCESS</code> = 0x91.</p> <p>In RNBRemote.h:</p> <pre><code>/* We translate the /usr/include/mach/exception_types.h exception types (e.g. EXC_BAD_ACCESS) to the fake BSD signal numbers that gdb uses in include/gdb/signals.h (e.g. TARGET_EXC_BAD_ACCESS). These hard coded values for TARGET_EXC_BAD_ACCESS et al must match the gdb values in its include/gdb/signals.h. */ #define TARGET_EXC_BAD_ACCESS 0x91 #define TARGET_EXC_BAD_INSTRUCTION 0x92 #define TARGET_EXC_ARITHMETIC 0x93 #define TARGET_EXC_EMULATION 0x94 #define TARGET_EXC_SOFTWARE 0x95 #define TARGET_EXC_BREAKPOINT 0x96 </code></pre> <p>and in RNBRemote.cpp:</p> <pre><code>// Translate any mach exceptions to gdb versions, unless they are // common exceptions like a breakpoint or a soft signal. switch (tid_stop_info.details.exception.type) { default: signum = 0; break; case EXC_BREAKPOINT: signum = SIGTRAP; break; case EXC_BAD_ACCESS: signum = TARGET_EXC_BAD_ACCESS; break; case EXC_BAD_INSTRUCTION: signum = TARGET_EXC_BAD_INSTRUCTION; break; case EXC_ARITHMETIC: signum = TARGET_EXC_ARITHMETIC; break; case EXC_EMULATION: signum = TARGET_EXC_EMULATION; break; case EXC_SOFTWARE: if (tid_stop_info.details.exception.data_count == 2 &amp;&amp; tid_stop_info.details.exception.data[0] == EXC_SOFT_SIGNAL) signum = tid_stop_info.details.exception.data[1]; else signum = TARGET_EXC_SOFTWARE; break; } </code></pre>

    1. CO:) thanks for replying! i'm writing my "module" from this tutorial and as i already commented my question earlier i'm already handling SIGSEV and SIGBUS but with no luck. i still can't handle EXC_BAD_ACCESS... try reading comments within that tutorial on cocoa with love... few people are having the same problem as me ...

    3. COTHANKS! really! :) this obviously can be a solution to this problem...but i'm sort of confused now, since i'm kind of a newbie to this, how can i handle it? :) calling signal(0x91, /*handler) didn't help... i must look stupid now :)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
