Description Matthias Klose 2021-05-03 06:23:31 UTC 
seening this with gdb 10.2 and gcc 10.3.0 on Ubuntu 21.04, using glibc 2.33, binutils 2.26.1 and gcc 10.3.0.

A lot of tests in the guality test suite time out after 300 seconds (the default dejagnu timeout). These tests, like pr36728-1.c run ok on other architectures (and fail), but timeout on armhf.

for gcc,

RUNTESTFLAGS=guality.exp=pr36728-1.c make -e -C <build>/gcc check-gcc


The last "successful" gcc-10 build is from April, using a gdb snapshot taken from the gdb-10 branch on March 05 2021.

Architectures like x86_64, powerpc64le, s390x, aarch64 are not affected.
Comment 1 Matthias Klose 2021-05-05 10:40:21 UTC 
this is "fixed" in the glibc 2.33 branch, if I understand the glibc maintainers correctly, they consider this as a workaround (see PR27744).
