Subject: libglib2.0-0: function g_ascii_strtoll is broken
Package: libglib2.0-0
Version: 2.12.4-2
Severity: normal
*** Please type your report below this line ***
g_ascii_strtoll is broken in 2.12.4, which comes streamline with Etch.
Patch for this is included.
The implementation has been changed (I don't know exactly when) to cope
with errors while converting negative values. The proposed patch to
glib/gstrfuncs.c "upgrades" the function to the correct implementation
that can be found, for example, in 2.16.3.
Tests for it were added as well. In particular, there are more tests
than in 2.16.3 (including those present in 2.16.3, anyway), because
two tests for near-the-limit values were added. If you execute the
patched test file in a non-patched system, you'll get an error.
Cheers,
Flavio Poletti.
