DrMemory is a tool for detecting memory errors and misuse of Windows APIs.
I tried portable version 1.8.1RC1 on 32-bit Windows 7 (it doesn’t support Windows 10 or 64-bit Windows).
I ran it as:
mkdir ..\drmemlogs..\drmemory\bin\drmemory.exe -logdir ..\drmemlogs -suppress=drmem-sup.txt — .\rel\SumatraPDF.exe ..\f1.pdf
There are some apparent false positives. I add suppressions to
drmem-sup.txt as I find them.DrMemory visibly slows down the program and also crashes sometimes (e.g. it crashed for me with XPS files).
