see above
These files are attached as background, and to identify the problem.
1-Src-Obj-Exe.zip --> to run the program and see abend, or to recompile.
SolarSniff is a pgm (beginning in development) to get MY rooftop data--
(a) more frequently: every 10 sec rather than 15 min,
(b) more detail: for each panel rather than one total.
2-GCC-LD-Log.txt --> showing Version....& what was used during compile and
link.
MinGW64 on Win7 on Lenovo X1 with Intel Core i7-2620M cpu and 8gb ram.
Probably can recompile on any Windows box with MinGW64.
3-EXE-x64dbg-Log.txt --> console messages, runtime environment log and data.
x64dbg log->DLL-s all loaded, then abend in ntdll with Invalid Address.
Probably reproduce abend on any Windows box. Need GDB/WinDbg/x64dbg to
see.
4-DOCs-about-idata.doc -->Authors and writers about PE/.idata section
Russinovitch, Windows Internals, confirms dll-s all loaded/in Post-Import.
MS PE/COFF Spec, Rev 11 Jan 23, 2017 Exerpt shows structures, &NUL fence.
Import data section, needs NUL fence,
from blog.kowalczyk.info/articles/pefileformat.html
5-DUMPidata.zip --> .idata Formatted hex dump of Modules section,
DUMPidata tool source code.
Shows Mod-1, Fence, Mod-2, Fence,
Mod-3, Fence, EXTRA-FENCE, Mod-4, NO-FENCE-CAUSES-ABEND
The Linker and BFD are too complex for me to determine where is the problem.
I need you to solve it from here.
