Sure. There is a segfault on the test for large precisions, on
"%.4000d". On libc5 this format works well until "%.1020d", but
segfaults for "%.1021d" and above. A severely trimmed down config.log.gz
comes attached. Here is the summary:
| checking for vasnprintf... no
| checking whether snprintf is declared... yes
| checking whether printf supports size specifiers as in C99... no
| checking whether printf supports 'long double' arguments... yes
| checking whether printf supports infinite 'double' arguments... no
| checking whether printf supports infinite 'long double' arguments... no
| checking whether printf supports the 'a' and 'A' directives... no
| checking whether printf supports the 'F' directive... no
| checking whether printf supports the 'n' directive... yes
| checking whether printf supports POSIX/XSI format strings with positions...
yes
| checking whether printf supports the grouping flag... yes
| checking whether printf supports the left-adjust flag correctly... yes
| checking whether printf supports the zero flag correctly... no
| checking whether printf supports large precisions... no
| checking whether printf survives out-of-memory conditions... no
| checking for snprintf... yes
| checking whether snprintf respects a size of 1... no
| checking whether _snprintf is declared... no
| checking for vasprintf... yes
Alain.
