And I guess I succeeded in getting at least the "stack overlow" variant. This combined with rr-debugger and an old but modified version of gdbinit.py I reached in winedevice.exe a segfault. (rr) bt #0 0x7e154db0 in SetupCloseLog () #1 0x7bc54b16 in call_dll_entry_point () #2 0x7bc59381 in MODULE_InitDLL () ... Some notes, the backtrace and singlestepping through SetupCloseLog showing the esp register are in attached file. It is a build without mingw compilers and from flags without much debug information, but function SetupCloseLog is quite short with just a few function calls. As far as I see the esp register has "just" the wrong value when the ret instruction is reached. Unfortunately I cannot point exactly to a single instruction which might be wrong. Maybe someone with better assembly knowledge can have a look? -- Do not reply to this email, post in Bugzilla using the above URL to reply.
