Hi, I'm trying to use Open Office from my C#/Mono application. I can get XComponentContext, using uno.util.Bootstrap.bootstrap(), when calling it first time, but application crashes, if I'm trying to do it second time (gots SIGSEGV somewhere in native code). Is there any problem in my code. Open Office API documentation doesn't contain any clue about need of any preparation for second call (for example, release of some resources). Of course, it doesn't make sens to call bootstrap() two times in row, but it can be necessary, if i want interact with Open Office in different parts of my application, but I guess SIGSEGV is not appropriate result anyway. My code: XComponentContext context = uno.util.Bootstrap.bootstrap(); context = uno.util.Bootstrap.bootstrap(); Here's stack strace: Stacktrace: at (wrapper managed-to-native) uno.util.Bootstrap.native_bootstrap () <0x00004> at (wrapper managed-to-native) uno.util.Bootstrap.native_bootstrap () <0xffffffff> at uno.util.Bootstrap.bootstrap () <0x0000d> at Izsaukums.MainClass.Main (string[]) [0x00000] in /home/janis/Desktop/ABC/Izsaukums/Izsaukums/Main.cs:1 at (wrapper runtime-invoke) Izsaukums.MainClass.runtime_invoke_void_object (object,intptr,intptr,intptr) <0xffffffff> Native stacktrace: /usr/bin/mono() [0x80ca6e4] /usr/bin/mono() [0x80f6893] [0xb76e9410] /usr/lib/ure/lib/libcli_uno.so(uno_ext_getMapping+0x1b2) [0xb3308042] /usr/lib/openoffice/basis-link/ure-link/lib/libuno_cppu.so.3(+0x1809e) [0xb688709e] /usr/lib/openoffice/basis-link/ure-link/lib/libuno_cppu.so.3(+0x1855b) [0xb688755b] /usr/lib/openoffice/basis-link/ure-link/lib/libuno_cppu.so.3(uno_getMapping+0xbd6) [0xb68881c2] /usr/lib/openoffice/basis-link/ure-link/lib/libuno_cppu.so.3(uno_getMappingByName+0x91) [0xb6888294] /usr/lib/openoffice/basis-link/ure-link/lib/libcli_uno_glue.so(+0x118c) [0xb6a6218c] /usr/lib/openoffice/basis-link/ure-link/lib/libcli_uno_glue.so(native_bootstrap+0x2c) [0xb6a6245c] [0xb7032a4e] [0xb703294e] [0xb70322bf] [0xb7032204] /usr/bin/mono(mono_runtime_exec_main+0xde) [0x8113b1e] /usr/bin/mono(mono_runtime_run_main+0x15a) [0x811429a] /usr/bin/mono(mono_main+0x18c4) [0x80b3524] /usr/bin/mono() [0x805ad25] /lib/tls/i686/cmov/libc.so.6(__libc_start_main+0xe6) [0xb7473bd6] /usr/bin/mono() [0x805ac61] Debug info from gdb: [Thread debugging using libthread_db enabled] [New Thread 0xb430cb70 (LWP 4370)] [New Thread 0xb4b67b70 (LWP 4369)] [New Thread 0xb62f0b70 (LWP 4351)] [New Thread 0xb6c3cb70 (LWP 4350)] [New Thread 0xb6c60b70 (LWP 4349)] 0xb76e9422 in __kernel_vsyscall () 6 Thread 0xb6c60b70 (LWP 4349) 0xb76e9422 in __kernel_vsyscall () 5 Thread 0xb6c3cb70 (LWP 4350) 0xb76e9422 in __kernel_vsyscall () 4 Thread 0xb62f0b70 (LWP 4351) 0xb76e9422 in __kernel_vsyscall () 3 Thread 0xb4b67b70 (LWP 4369) 0xb76e9422 in __kernel_vsyscall () 2 Thread 0xb430cb70 (LWP 4370) 0xb76e9422 in __kernel_vsyscall () * 1 Thread 0xb742a6f0 (LWP 4346) 0xb76e9422 in __kernel_vsyscall () Thread 6 (Thread 0xb6c60b70 (LWP 4349)): #0 0xb76e9422 in __kernel_vsyscall () #1 0xb75ea736 in nanosleep () at ../sysdeps/unix/syscall-template.S:82 #2 0x081a6af8 in ??
