A Crash About Heap Corruption
Posted: Sat Jan 04, 2020 7:36 am
Dear developer:
I got a crash about the nconvert，the specific information is as follows:
1. program: the latest version of the nconvert(command: nconvert.exe -out jpeg -truecolors sample) and xnview(xnconvert.exe)
2. system: windows7-32/64
3. description: The crash occurs when function free() is called. I think the cause of the crash is heap corruption and consequent access violation in the ntdllRtlpCoalesceFreeBlocks call when heap trying to combine two unused bocks into a bigger one.
If necessary I can provide the file that causes the crash.
