Hmm.... if this is on working code that's a bug. Can you try to reduce your CMakeList to find why it thinks the parens are not balanced?

I encountered the same issue, I'll try to get a reproduceable example

[codeling]

Same issue here. Anyone got a clue what the problem might be already?

[dascandy]

Still no idea what kind of code leads to this assert; have only seen this bug report but no examples yet.

If number of closing parenthesis is bigger than number of opening parenthesis, and file stream is at eof, then parenLevel will be equal to -1.

Hi,

I'm experiencing the same issue. I found following subprojects used in my project caused the exception:

https://github.com/webmproject/libwebp / tag v1.2.4 (current HEAD also fails)
https://github.com/gabime/spdlog.git / tag v1.10.0 (current HEAD also fails)

based on grep results CMakeLists.txt of those projects have inconsistent number of opening and closing parens.

Found it. It triggers on

option(
SPDLOG_NO_ATOMIC_LEVELS
"prevent spdlog from using of std::atomic log levels (use only if your code never modifies log levels concurrently"
OFF)

in spdlog. Note the unbalanced parenthesis in the comment. Will fix.

Hi, thank you for spending time fixing this. The fix is actually working for spdlog.
However it won't for libwebp. Please check #63
