Overflowing calculations with constants are compiled to invalid code
-------------------------------------------------------------------- Key: BOO-1251 URL: http://jira.codehaus.org/browse/BOO-1251 Project: Boo Issue Type: Bug Components: Compiler Environment: Boo 0.9.2.3383 on .NET 3.5 SP1 Reporter: Daniel Grunwald Priority: Minor Fix For: 0.9.3 In booish, enter "1 << 0x22". Expected result: 4 (due to integer overflow) Actual result: System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. Compiling the code and running PEVerify reveals that the Boo compiler emitted invalid code. [IL]: Error: [d:\Net\boo\bin\a.exe : AModule::Main][offset 0x00000009][found Long][expected Int32] Unexpected type on the stack. 1 Error Verifying a.exe Everything works fine when using variables - the bug seems to be related to constant folding. The same error occurs for other integer calculations that cause overflows (e.g. multiplications). -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.codehaus.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira --------------------------------------------------------------------- To unsubscribe from this list, please visit: http://xircles.codehaus.org/manage_email |
