I compiled with gcc4 and linux and couldn't observe crashes during rotation.

Thanks for information.
I tried the version on nightly site, and they didn't crash.

It seems to happen only with my compiled version. (msys MinGW gcc3)

This look most liekely like an access at an illegal halthandle_t. But is is hard to debug. You may try valgrind to find this error.

Sorry, I can't understand the meaning what you said.
This also happen with startup map, which don't have halt.

valgrind is a tools to find illegal pointer access (but only for Linux

)

quickstones are only used for convoi pointers and halt pointers. Thus such an acess con be only due to a convoi or a halt (and oil rigs would be halts too). But I am not sure, what goes wrong here.
