Subject: Increase the amount of data tested in stdio-common/tst-fwrite-pipe.c
X-Git-Tag: glibc-2.42~451
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=4734d0f8adde573aeafe79ad0c71807833db1cae;p=thirdparty%2Fglibc.git

Increase the amount of data tested in stdio-common/tst-fwrite-pipe.c

The number of iterations and the length of the string are not high
enough on some systems causing the test to return false-positives.

Testcase stdio-common/tst-fwrite-bz29459.c was fixed in the same way in
1b6f868625403d6b7683af840e87d2b18d5d7731
(Increase the amount of data tested in stdio-common/tst-fwrite-bz29459.c, 2025-02-14)

Testcases stdio-common/tst-fwrite-bz29459.c and stdio-common/tst-fwrite-pipe.c
were introcued in 596a61cf6b51ce2d58b8ca4e1d1f4fdfe1440dbc
