The test shows that there are problems in seti_parse_wu_header.
--------------------------------
here is the Callers graph
main ---> it goes to worker()
run_stage = POSTINIT;
retval = boinc_init();
if ( !retval ) worker(); <-------
worker.cpp(239): retval = read_wu_state(); <------
read_wu_state() <--------
Calls to 'seti_parse_wu' ----->
worker.cpp(136): retval = seti_parse_wu( f, analysis_state );
Calls to 'seti_parse_wu_header' ----->
seti.cpp(1004): retval = seti_parse_wu_header( f );
before the statement
buffer += buf;
debugger show: --->
+ buf 0x0012edc4 "</workunit_header>

after the statement above we can see tha last entry
</workunit_header>
is done now..... so far OK
if ( wu ) delete wu;
wu = new workunit( buffer );
<-------------- here is a problembuffer is filled properly
it starts with --->

-------------------------------------------------------
ok
now we entry the statement
and switch to dbgnew.cpp
55 void *res = _nh_malloc_dbg( cb, 1, nBlockUse, szFileName, nLine );
we see all parameters are properly filled
cb 1544 unsigned int
nBlockUse 1 int
nLine 254 int
res 0x00000000 void *
+ szFileName 0x005db0e8 "..\seti_header.cpp" const char *
now we execute 55
we switch to dbgheap.c
269 void * pvBlk = _nh_malloc_dbg_impl(nSize, nhFlag, nBlockUse, szFileName, nLine, &errno_tmp);
we see all parameter are properly filled

now we execute 269
we switch to

all parameters are properly filled

nhFlag 1 int
pvBlk 0x00000001 void *
+ szFileName 0x005db0e8 "..\seti_header.cpp" const char *
and execute 239
and come back
pvBlk 0x0037ab58 void *
how we can see pvBlk is filled
allocation was sucessful and we came back from dbgnew.cpp
66 return res;
res 0x0037ab58 void *

so we go on and come to xmemory
pointer allocate(size_type _Count)
{ // allocate array of _Count elements
return (_Allocate(_Count, (pointer)0));
debug shows ---->

we switch to dbgheap

Unhandled exception at 0x7c91eddd in seti_boinc.exe: 0xC0000005: Access violation writing location 0x00030ffc.--------------------------------
wieso da nach 0x00030ffc geschrieben wird ist mir noch unklar
there again the errors:
First-chance exception at 0x7c93a321 in seti_boinc.exe: 0xC00000FD: Stack overflow.
First-chance exception at 0x7c812a7b in seti_boinc.exe: Microsoft C++ exception: std::bad_alloc at memory location 0x000337e4..

Unhandled exception at 0x7c91eddd in seti_boinc.exe: 0xC0000005: Access violation writing location 0x00030ffc.
------------------------------------------------
we look after blockSize
found in dbgheap.c line 421
421 blockSize = sizeof(_CrtMemBlockHeader) + nSize + nNoMansLandSize;
debug shows ----->
nSize = 7248
_CrtMemBlockHeader = {pBlockHeaderNext=??? pBlockHeaderPrev=??? szFileName=??? ...}
blockSize = 7284
nNoMansLandSize ----> can´t find it
--------------------------------------------------
uhhhhhhhhhh.... must search
any suggestions
