2013-11-06preprocessor/58580 - preprocessor goes OOM with warning for zero literalsDodji Seketeli6-34/+127
In this problem report, the compiler is fed a (bogus) translation unit in which some literals contain bytes whose value is zero. The preprocessor detects that and proceeds to emit diagnostics for that king of bogus literals. But then when the diagnostics machinery re-reads the input file again to display the bogus literals with a caret, it attempts to calculate the length of each of the lines it got using fgets. The line length calculation is done using strlen. But that doesn't work well when the content of the line can have several zero bytes. The result is that the read_line never sees the end of the line because strlen repeatedly reports that the line ends before the end-of-line character; so read_line thinks its buffer for reading the line is too small; it thus increases the buffer, leading to a huge memory consumption, pain and disaster. The patch below introduces a new get_line function that returns the next line of a file and return the length of that line even if the line contains zero bytes. That get_line function has been adapted from the getline function from the GNU C Library because getline being a GNU extension it is not necessarily supported on all platforms. read_line is then modified to return the length of the line along with the line itself, as the line can now contain zero bytes. Callers of read_line are adjusted consequently. diagnostic_show_locus() is modified to consider that a line can have characters of value zero, and so just shows a white space when instructed to display one of these characters. gcc/ChangeLog: * input.h (location_get_source_line): Take an additional line_size parameter. * input.c (get_line): New static function definition. (read_line): Take an additional line_length output parameter to be set to the size of the line. Use the new get_line function do the actual line reading. (location_get_source_line): Take an additional output line_len parameter. Update the use of read_line to pass it the line_len parameter. * diagnostic.c (adjust_line): Take an additional input parameter for the length of the line, rather than calculating it with strlen. (diagnostic_show_locus): Adjust the use of location_get_source_line and adjust_line with respect to their new signature. While displaying a line now, do not stop at the first null byte. Rather, display the zero byte as a space and keep going until we reach the size of the line. gcc/testsuite/ChangeLog: * c-c++-common/cpp/warning-zero-in-literals-1.c: New test file. From-SVN: r204453
