[Bug other/8822] internal error segmentation fault on dual-systems


------- Additional Comments From dieter dot ferdinand at gmx dot de  2003-12-06 20:31 -------
hello,
i have installed the new version last week and make some test with 2 cpu's 
active.

at the first compilation, the compiler breaks some times by compiling itself.

when i boot the system as single-cpu-system, there are no problems, but when i 
activate the second cpu the compiler crashs with different error-messages.

i think, that there are one ore more variables are not initialisized, when a 
new thread starts, while the thread is started, before all variables are 
initialized.

i will try the option --disable-hreads and hope, the threading of the compiler 
self is disabled with them.

please try to compile gcc on a multiprocessor-system some times to get the same 
errors.

this error comes also by compiling other big programs, but most time at an 
other position of the compilation process.

i don't think, that this is a bug by my hardware (all programms runs error free 
on this system, also multithreading programs. only gcc makes errors), but i 
have other dual-systems, on which i can test it in next time. i use this 
systems normaly under win2000 to convert video-files an this systems is stable.

there is no possibility to reproduce this error at a spezific point of a 
compilation. the only way, to fix all errors, which depend on the same problem 
is to check alle points, at which a new thread is started, that all variables, 
which transfered to this thread are initialized.

it is also possible, that the error comes with the uses threading lib, but i 
don't know, how i can check this, while all other multitreading programs, which 
i used, make no problems.

i use glibc 2.3.2 and i have updated all other libs in the last 6 month to the 
newest version.

goodby
