Attempt to resolve Assertion failed: (total_read == rv_get_reg(rv, rv_reg_a2))

[huaxinliao]

At the outset, I attempted to replicate the issue reported by qwe661234. However, on my PC, everything appeared normal without any errors. To further investigate, I utilized GDB by specifying the build/rv32emu and setting a breakpoint at src/syscall.c:290. My goal was to observe the values of 'total_read' and 'rv_get_reg (rv, rv_reg_a2)' to ascertain whether any discrepancy in these values might have been the root cause of qwe661234's issue. Upon analysis, I discovered that 'total_read' was equal to 0xC, and 'rv_get_reg(rv, rv_reg_a2)' was also 0xC. Consequently, in the assertion 'assert(total_read == rv_get_reg(rv, rv_reg_a2));', the program didn't halt. The link is my debug report.

See #214

I have chedcked the values of total_read and rv_get_reg(rv, rv_reg_a2). The values of total_read and rv_get_reg(rv, rv_reg_a2) are the same

Kindly offer well-articulated remarks on your opinions and proposed modifications. Make them informative.

After git checkout to commit 567660c, I also did not observe the assertion failure mentioned in the issue during my tests. Tested on Ubuntu 22.04.3 LTS.
