| Summary | 0000862: Segmentation fault during startup | ||||
| Description | I compiled and installed revision 2aa52c15942c6edfcd32dce6e391043c0caa36ab with morgengrauen settings and I get a segmentation fault during the startup. The option --with-malloc=sysmalloc fixes the issue, but I'll send you the stacktrace and driver log anyway. | ||||

Thank you! It seems, we have yet another interference between system libs and our own malloc implementation. Our default replacement of the system malloc seems to get increasingly problematic. Maybe we will find another solution, but we will probably change that default soon... |
|
|
The driver now uses by default the system memory allocator, not our own allocator. This solves the immediate issue. (Rewriting our memory allocator would solve the fundamental issue, but that has to wait...) |
