A global-buffer overflow occurs in commit fbef90a7039b994907db34fde50f6fa5e46ab535 (ASAN on). System info: ubuntu 18.04, x86-64 Without ASAN, tcc will encounter a segment fault due to this overflow.
Actually you won't get a segfault but an abort, due to an assert triggering. That is fine. Nevertheless it's nicer to not do out-of-bounds array accesses, so I've fixed that in mob. Thanks for the report.
Ciao, Michael.
