Bug#970862: php-imagick cannot be loaded by apache2: Cannot allocate memory in static TLS block

[Tilman Schröder <tilman.schroeder@gmx.de>]

Control: reassign -1 php-imagick

Hi,

according to [1] this is a bug in "whatever dlopened libgomp.so.1 and
before doing that ate all the preallocated TLS area.", so yes, it seems
to be a bug in php, php-imagick, or even apache2-bin (I do not know, I
am not an experienced programmer).

However, I was able to fix this for my setup by adding the line
export LD_PRELOAD="libgomp.so.1:${LD_PRELOAD}"
to /etc/apache2/envvars and now everything runs fine.

From my point of view, you can either tag this bug as fixed or wontfix,
as you prefer.

Sincerely,
procyon
