Revision 1.2 2006/01/22 22:47:15 eskimo1
|
|||
|
|
Significant rewrite to account for changes in MoreBacktrace. Still not as functional as I'd like.

Revision 1.1 2003/04/04 15:03:00 eskimo1
|

|
|
First checked in. This code still has bugs, but I've written enough code that checking in is a good idea.

// IMPORTANT:
|
|||
|
|
// This code is currently broken in two ways:
|
|||
|
|
//
|
|||
|
|
// o If the binary has debugging symbols, you often get a debugging
|
|||
|
|
// symbol rather than a real symbol. I believe this is caused by
|
|||
|
|
// handling of N_FUN in the GetFunctionName routine. Furthermore,
|
|||
|
|
// I believe that it did work previous but something changed in the
|
|||
|
|
// Mach-O headers to break it. This warrants serious investigation.
|
|||
|
|
//
|
|||
|
|
// You can work around this problem by removing the debug symbols
|
|||
|
|
// using:
|
|||
|
|
//
|
|||
|
|
// $ strip -S YourBinaryName
|
|||
|
|
//
|
|||
|
|
// o It doesn't handle 64-bit Mach-O binaries. This is a simple
|
|||
|
|
// limitation of the code, and it should be relatively easy to fix.
|
|||
|
|
//
|
|||
|
|
// I intend to fix both of these problems with a future rewrite.
|
|||
|
|
// Until then, I've decided to live with them.
