Weird, all it does is call typeid, could that be the issue?

I am afraid it indeed might be the culprit. At least it always faults on type_info::name(void) but with different strange errors, such as Free Heap block at .... modified at ... after it was freed First chance exception in regex_regress_threaded.exe (MSVCRTD.DLL): 0xC0000005: Access Violation Unfortunately the guys from MS forgot to supply the relevant library source for these calls, so I can only guess. Could it be, that typeid(...) or .name() are not thread safe on msvc-6.5 altough they are located in the thread safe version of the runtime lib? Do you have an idea what could be tried to prove or disprove this hypothesis? Roland
