Hi everyone,
first thanks for your help in debugging aMule by providing a backtrace(BT). But I'm sorry to say that the BTs aMule produces on normal execution
OOPS! - Seems like aMule crashed
--== BACKTRACE FOLLOWS: ==--
[...]are not very useful.
To produce a useful BT you need to follow these steps:
[list=1]
- Make sure you have installed "gdb" and the needed libs to compile aMule.
- Compile aMule with debugging information:
- ./configure --enable-debug --disable-optimise --prefix=/where/to/install/aMule
- make
- make install
- Run "gdb /where/to/install/aMule/bin/amule".
- Enter "ha SIGPIPE nostop noprint pass" after (gdb) prompt (to avoid gdb stopping at broken pipes).
- Enter "run".
- Use aMule normally until it segfaults.
- Enter "bt".
- Enter "bt full".
- Post the output of the last two steps here with some additional comment about the circumstances the segfault happened and what aMule version you used (checkout time for CVS).
A good BT should look like this (shortened):
Program received signal SIGSEGV, Segmentation fault.
